Pseudocode for the program
// Declaring variables
Declare Integer InternetHits[10]
Declare Integer i
// Loop for inputting values
For i = 0 to 9
Print 'Enter the value-' Print i+1
Input InternetHits[i]
End For
// End of Program.

1. #include <stdio.h> 2. int main () { 3. int internetHits[10]; 4. int hits; 5. int counter; 6. for(counter=0;counter<10;counter++){ 7. printf("Enter number of hits: "); 8. scanf("%d",&internetHits[counter]); 9. } 10. //Display Values 11. printf("Entered values are: \n"); 12. for (counter = 0;counter<10;counter++){ 13. printf("%d\n",internetHits[counter]); 14. } 15. return 0; 16. }

Question

Design and write a program, using functions, that calculates the area and perimeter of a rectangle whose dimensions (length and width) are provided by a user.
There are 4 components of your submission including:
Program Description- A detailed, clear description of the program you are building.
Analysis- Demonstrates your thought process and steps used to analyze the problem. Be sure to include the required input and output and how you will obtain the required output from the given input? Also, include your variable names and definitions. Be sure to describe the necessary formulas and sample calculations that might be needed. Talk about how your design will allow any number of students and final grades to be possible inputs.
Test plan - Prepare at least 3 sets of input data (Test data) along with their expected output for testing your program. Your test data can be presented in the form of a table as follows (note: feel free to adapt to your design)
Pseudocode- Provide pseudocode of your overall design that fulfills the requirements of the project
All of these components should be placed in word document for submission.

Provided 4 components as per your requirements.
1) Program Description: * Read input for length and width of the rectangle values from the user. * Calculate the area and perimeter values by using functions. * Display the area and perimeter of the rectangle.
C Program Code:
//Header file section
#include<stdio.h>
//Function prototypes float calcArea(float length, float width); float calcPerimeter(float length, float width);
//main method int main()
{
//Declare variables float length,width; float resArea,resPer;
//Prompt and read input from the user printf("Enter length of the rectangle: "); scanf("%f",&length); while(length<0)
{
printf("Enter Length Again {Negative Values Not Allowed}: "); scanf("%f",&length);
}
printf("Enter width of the rectangle: "); scanf("%f",&width); while(width<0)
{
printf("Enter Width Again {Negative Values Not Allowed}: "); scanf("%f",&width);
}
resArea=calcArea(length,width); resPer=calcPerimeter(length,width); //Display output printf("Area of a rectangle = %.2f \nPerimter of a rectangle= %.2f \n",resArea, resPer); return 0;
}
//Function definition of calcArea to compute the area of a rectangle area =l*b float calcArea(float length, float width)
{
return length*width;
}
//Function definition of calcPerimeter to compute the perimeter of a rectangle p =2(l+b) float calcPerimeter(float length, float width)
{
return 2*(length+ width);
}
2) Analysis:
Program contains three modules: main, calcArea, and calcPermiter.
In main: * Declare variables: length,width, resArea, and resPer. * Prompt and read the length of the rectangle and width of the rectangle from the user. * Check the input values are negative or not. If it is negative, again read the positive values otherwise go to call the functions, calcArea, and calcPermiter. * CalcArea function result stored in variable, resArea and calcPermiter function result stored in resPer. * Display the output as the area and perimeter values of a rectangle. calcArea function: * The function calcArea accepts the length and with parameter values and calculate the area of the rectangle by using formula: length*width. Finally return the result. calcPermiter function: * The function calcArea accepts the length and with parameter values and calculate the perimeter of the rectangle by using formula: 2*(length+ width). Finally return the result.
3) Test plan:
Prepared three sets of input data (Test data) along with their expected output for testing your program. Your test data can be presented in the form of a table as follows:

Sample Output screen shot: 4) Pseudocode:
Module main () Declare width, length, resArea, resPer as float Display “Enter length of the rectangle:“ Input length Display “Enter width of the rectangle:“ Input width resArea = calcArea(length,width) resPer = calcPerimeter(length, width) Print resArea, resPer
End Main
Module calcArea(length,width) Return with length*width
End calcArea
Module calcPerimeter(length, width) Return with 2*(length+ width);
End calcPerimeter
