Given a double variable named x that has been declared and given a value, let's use a binary search technique to assign an estimate of its square root to another double variable, root that has also been declared. Let's assume that x's value is greater than 1.0 -- that will simplify things a bit. Here's the general idea:

Since x>1, we know its square root must be between 1 and x itself. So declare two other variables of type double (a and b say) and initialize them to 1 and x respectively. So we know the square root must be between a and b. Our strategy is to change a and b and make them closer and closer to each other but alway make sure that the root we're looking for is between them. (Such a condition that must always hold is called an invariant.)

To do this we will have a loop that at each step finds the midpoint of a and b. It then squares this midpoint value and if the square of the midpoint is less than x we know that the root of x must be bigger than this midpoint: so we assign the midpoint to a (making a bigger and shrinking our a and b interval by half!)-- and we still can be sure that the root is between a and b. Of course if the midpoint's square is greater than x we do the opposite: we assign b the value of midpoint.

But when to stop the loop? In this exercise, just stop when the interval between a and b is less than 0.00001 and assign root the midpoint of a and b then.

We call this a binary search also because at each stage we cut the interval under consideration in half. Efficient as this method is, old Isaac Newton discovered an algorithm that is even more efficient and that's what the library function sqrt uses.

Answer: const double PRECISION = 0.00001; double a = 1; double b,mid; b=x; while ((b-a)>PRECISION)
{
root = (a+b)/2; if (root*root < x) a = root; else b=root;
}

55. Given an array arr of type int , along with two int variables i and j , write some code that swaps the values of arr[i] and arr[j] . Declare any additional variables as necessary.
Answer:
int temp=arr[i]; arr[i]=arr[j]; arr[j]=temp;

56. Write the definition of a function named isSorted that receives three arguments: an array of int, an int that indicates the number of elements of interest in the array, and a bool.

If the bool argument is true then the function returns true if and only if the array is sorted in ascending order. If the bool argument is false then the function returns true if and only if the array is sorted in descending order. In all other cases the function returns false.

You may assume that the array has at least two elements.
Answer:
bool isSorted(int a[], int n, bool status)
{
bool flag = true; if(status == true) { for (int i=0; i<n-1; i++) if (a[i] > a[i+1]) flag = false; } else { for (int i=n-1; i > 0; i--) if (a[i] > a[i-1]) flag = false; } return flag;
}

57. Assume you have a int variable n that has already been declared and initialized. Its value is the number of integers that need to be read in from standard input and printed out in sorted (ascending) order, each on a line by itself. Furthermore, there are no duplicates in the input and every number to be read is a non-negative value that is less than n's value.

In this exercise you may not use any array (or fancy STL collection such as a vector). You may declare a variable or two as needed. With these restrictions, read the n values and print them out as required onto standard output.
Answer:
int x=0;

for (int i=0; i<n; i++)
{
cin >> x; cout << i << "\n";
}
58. Write a fragment of code that reads in integers from standard input, until end-of-file and sends their (floating point) average to standard output. If no numbers are input, the message “no values to average” is printed instead (while loops, end-of-file processing, mixed-mode arithmetic, basic conditional)
Answer:
float number=-1; float count=0; float sum=0;

while(cin.eof()==false)
{
cin >> number; sum += number; count++;
}

if(number==-1)
{
cout << "no values to average";
}
else{ if (count>0) cout << sum/count;
}

59. You are given an array x of int elements along with an int variable n that contains the number of elements in the array. There are no duplicates in this array. You are also given an int variable m that has been declared. Assign to m the median value of the array.

NOTE: The median of a set of numbers is the number in the set such that there are as many numbers above that value as there are below. If the set has an even number of members, the median is the average of the pair of numbers such that there are as many numbers above the pair as there are below.

EXAMPLE 1: Given 5 8 1 9 7 the median is 7 because there are two numbers below (1 5) and two numbers above (8 9).

EXAMPLE 2: Given 3 7 1 4 6 9 the median is the average of 4 and 6 because there are two numbers above 4 and 6 (7 9) and two numbers below (3 1).
Answer:
int temp;

for (int i=0; i<n; i++)
{
for (int j=i+1; j<n; j++) { if (x[i]>x[j]) { temp=x[j]; x[j]=x[i]; x[i]=temp; } }
}

if (n % 2==0) m=(x[(n/2)-1] + x[(n/2)]) / 2; else m=x[n/2];

60. You are given an array x of string elements along with an int variable n that contains the number of elements in the array. You are also given a string variable mode that has been declared. Assign to mode the mode value of the array. (Assume there are no "ties".)

NOTE: The mode is the value that occurs most frequently.

EXAMPLE: Given "msft" "appl" "msft" "csco" "ibm" "csco" "msft", the mode is "msft" because it appears the most number of times in the list.
Answer:
string temp; string test; int count=1; int max=1;

for (int i=0; i<n; i++) for (int j=0; j<n; j++) if (x[i]>x[j]) { temp=x[i]; x[i]=x[j]; x[j]=temp; }

test = "-"; max=0; count=0;

for (int i=0; i<n; i++) { if (x[i]==test) { count++; if (count>max) { mode=test; max=count; } } else { test=x[i]; count=1; } } 61. Modify the solution to exercise 11186 so that it can handle duplicates in the input. Hint: change the bool array to an array of int. The instructions for 11186 are repeated below:

11186: In this exercise, you will write some code that reads n unique (no duplicates!) non-negative integers, each one less than fifty (50). Your code will print them in sorted order without using any nested loops-- potentially very efficient! We'll walk you through this:

First, assume you are given an int variable n, that contains the number of integers to read from standard input.

Also assume you are given an array, named wasReadIn, of fifty (50) bool elements and initialize all the elements to false.

Third, read in the n integers from the input, and each time you read an integer, use it as an index into the bool array, and assign that element to be true-- thus "marking" in the array which numbers have been read.

Lastly the "punchline": write a loop that traverses the bool array: every time it finds an element that is true it prints out the element's INDEX -- which was one of the integers read in. Place all the numbers on a single line, separated by a single spaces. Note: this technique is not limited to 50 elements-- it works just as well for larger values. Thus, for example you could have an array of 1,000,000 elements (that's right-- one million!) and use it to sort numbers up to 1,000,000 in value!
Answer:
int number;

for (int i=0; i<50; i++)
{
wasReadIn[i]=0;
}

for (int i=0; i<n; i++)
{

62. In this exercise, you will write some code that reads n unique (no duplicates!) non-negative integers, each one less than fifty (50). Your code will print them in sorted order without using any nested loops-- potentially very efficient! We'll walk you through this:

First, assume you are given an int variable n, that contains the number of integers to read from standard input.

Also assume you are given an array, named wasReadIn, of fifty (50) bool elements and initialize all the elements to false.

Third, read in the n integers from the input, and each time you read an integer, use it as an index into the bool array, and assign that element to be true-- thus "marking" in the array which numbers have been read.

Lastly the "punchline": write a loop that traverses the bool array: every time it finds an element that is true it prints out the element's INDEX -- which was one of the integers read in. Place all the numbers on a single line, separated by a single spaces. Note: this technique is not limited to 50 elements-- it works just as well for larger values. Thus, for example you could have an array of 1,000,000 elements (that's right-- one million!) and use it to sort numbers up to 1,000,000 in value!
Answer:
int number;

for (int i=0; i<50; i++) wasReadIn[i]=0;

for (int i=0; i<n; i++)
{
cin >> number; wasReadIn[number]=1;
}

for (int i=0; i<50; i++)
{
if (wasReadIn[i]==1) cout << i << " ";
}

63. Write a statement to declare and initialize an array of int named denominations that contains exactly six elements.

Your declaration statement should initialize the elements of the array to the following values: 1, 5, 10, 25, 50, 100. (The value 1 goes into the first element; the value 100 to the last.)
Answer:
int denominations[6] = {1,5,10,25,50,100}; 64. Given an array temps of double , containing temperature data, and an int variable n that contains the number of elements in temps :

Compute the average temperature and store it in a variable called avgTemp .

Besides temps , n , and avgTemp , you may use only two other variables -- an int variable k and a double variable total , which have been declared.
Answer:
total=0; for (k=0; k<n; k++)
{
total += temps[k];
}

avgTemp =total/n; 65. We informally define the term "corresponding element" as follows: The first element in an array and the last element of the array are corresponding elements. Similarly, the second element and the element just before the last element are corresponding elements. The third element and the element just before the element just before the last element are corresponding elements -- and so on.

Given an array a and a variable n that contains the number of elements in a , write an expression for the corresponding element of a[i] .
Answer:
a[n-i-1] 66. Reversing the elements of an array involves swapping the corresponding elements of the array: the first with the last, the second with the next to the last, and so on, all the way to the middle of the array.

Given an array a , an int variable n containing the number of elements in a , and two other int variables, k and temp , write a loop that reverses the elements of the array.
Answer:
for (int k=0; k<n/2; k++)
{
temp=a[k]; a[k]=a[n-k-1]; a[n-k-1]=temp;
}
67. An array of integers named parkingTickets has been declared and initialized to the number of parking tickets given out by the city police each day since the beginning of the current year. (Thus, the first element of the array contains the number of tickets given on January 1; the last element contains the number of tickets given today.)

A variable named ndays has been declared and initialized to hold the size of the array. (Thus, if today were January 18, ndays would have the value 18; if today were February 3, ndays would have the value 34.)

In addition, a variable named mostTickets has been declared, along with a variable k .

Without using any additional variables, and without changing the values of ndays or the elements of the parkingTickets array, write some code that results in mostTickets containing the largest value found in parkingTickets .
Answer:
mostTickets=0; for (k=0; k< ndays; k++)
{
if (parkingTickets[k]>mostTickets) mostTickets=parkingTickets[k];
}

68. Assume that two parallel arrays have been declared and initialized: healthOption an array of type char that contains letter codes for different healthcare options and annualCost an array of type int. The i-th element of annualCost indicates the annual cost of the i-th element of healthOption. In addition, there is an char variable, best2.Write the code necessary to assign to best2 the health option with the lower annual cost, considering only the first two healthcare options.

Thus, if the values of healthOption are 'B', 'Q', 'W', 'Z' and the values of annualCost are 8430, 9400, 7050, 6400 your code would assign 'B' to best2 because 8430 is less than 9400 and is associated with 'B' in the parallel array. (We ignore 'W' and 'Z' because we are considering only the first two options.)
Answer:
if (annualCost[0]<annualCost[1]) best2=healthOption[0]; else best2=healthOption[1]; 69. printArray is a function that has two parameters. The first parameter is an array of element type int and the second is an int , the number of elements in the array. The function prints the contents of the array parameter; it does not return a value.

inventory is an array of int s that has been already declared and filled with values. n is an int variable that holds the number of elements in the array.

Write a statement that prints the contents of the array inventory by calling the function printArray .
Answer:
printArray(inventory,n); 70. Write a statement that declares a prototype for a function printArray , which has two parameters. The first parameter is an array of element type int and the second is an int , the number of elements in the array. The function does not return a value.
Answer:
void printArray(int [], int); 71. Write the definition of a function printArray , which has two parameters. The first parameter is an array of int s and the second is an int , the number of elements in the array. The function does not return a value. The function prints out each element of the array, on a line by itself, in the order the elements appear in the array, and does not print anything else.
Answer:
void printArray (int s[],int n)
{
for (int k=0; k<n; k++) cout << s[k] << endl;

} 72. Write the definition of a function named sumArray that receives two parameters: an array of element type int and an int that contains the number of elements of the array. The function returns the sum of the elements of the array as an int .
Answer:
int sumArray (int s[], int n)
{
int sum=0; for(int k=0; k<n; k++) sum += s[k];

return sum;
}
73. Write the definition of a function, isReverse , whose first two parameters are arrays of integers of equal size, and whose third parameter is an integer indicating the size of each array. The function returns true if and only if one array is the reverse of the other. ("Reverse" here means same elements but in reverse order.)
Answer:
bool isReverse (int one[], int two[], int size)
{
int matches=0; for (int k=0; k<size; k++) { if (one[k] == two[size-k-1]) { matches++; } } if (matches==size) return true; else return false;
}
74. Write the definition of a function reverse , whose first parameter is an array of integers and whose second parameter is the number of elements in the array. The function reverses the elements of the array. The function does not return a value.
Answer:
void reverse (int a[], int n)
{
int temp; for (int k=0; k<n/2; k++) { temp=a[k]; a[k]=a[n-k-1]; a[n-k-1]=temp; }
}
