...operand . The operand (the value on which the operator operates ) of the unary operator must have arithmetic or pointer type and the result is the value of the argument. Example:- If a=5 then +a means 5 If a=0 then +a means 0. If a=-4 then +a means -4. Ternary operator:- It precedes an operand. The operand of the unary operator must have arithmetic type and the result is the negation of the operand’s value. Example:- If a=5 then –a means -5 If a=0 then –a means 0 If a=-4 then –a means 4. (b) Assignment and equalto operator Assignment operator:- Equal to operator: An assignment operator assigns value In this we put the To a variable. value as it is. Example – Example- a*=5 means a=5*5. Int a; a=5 means a is initialized with 5 if(a==5) { return true; } return false; (c) Expression and statement Expression:- An expression is any valid combination of operators , constants , and variables.

...Team B Calorie Count Tool PRG/211 May 5, 2014 Team B Calorie Count Tool PROBLEM STATEMENT Team B was asked to develop a program which would calculate the user’s daily intake of calories and measure those calories against the overall calories expended. The core purpose of this program will do two primary functions. First, it will record the user intake of calories as acquired through meals throughout the day. Second, the user will record caloric output associated with physical activity. This information will be calculated together to determine the caloric surplus or deficit for the user. In order for the program to execute accurately, and provide customized results, the user will be required to input personal data to include gender, age, weight, and height. This additional information is essential to determine the user’s default caloric burn rate, otherwise known as the basal metabolic rate (BMR). The BMR and the calories burned as a result of physical activity will be calculated against the intake of calories to determine the overall success for the user. As the program is executed it must: * Record user name, age, height, weight to enable more accurate calculations * Record the users specific caloric values entered for each meal * Record the user activity and caloric burn values for that activity * Calculate the basal metabolic rate (BMR) for the individual * Subtotal the total caloric values for the day * Combine the physical activity and...

...something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that adding or subtracting the same amount from both sides of an equation maintains equality. Kieran gives this example: Solve for x: 2x + 3 = 5 + x 2x + 3 – 3 = 5 + x 2x = 5 + x – x – 3 2x – x = 5 – 3 x = 2 The answer is correct, but several steps of the solution contain incorrect equations. In summary, a student with this misconception will: Assume the solution to a problem is the number after the...

...problems, different actions must be taken depending on the value of the data. The if statement in C I used to implement such s decision structure in its simplest form – that of selecting a statement to be executed only if a condition is satisfied. Syntax: if(condtion) statement executed if condition is true When an executing program encounters the if statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false. If the condition evaluates to any non-0 value (positive or negative), the condition is considered as a “true” condition and the statement following the if is executed; otherwise this statement is not executed. Relational Operators In C Relational operator | Meaning | Example | < | Less than | age < 30 | > | Greater than | height > 6.2 | <= | Less than or equal to | taxable <= 200000 | >= | Greater than or equal to | temp >= 98.6 | == | Equal to | grade == 100 | != | Not equal to | number !=250 | In creating relational expressions, the relational operators must be typed exactly as given in the above table.

...ACC 616 Prof. Robert Simpson Student name: On the back Assignment 1: Explain Assignment of Income Doctrine The "assignment of income" doctrine states that income is taxed to the one who actually earns it. That means a taxpayer cannot avoid tax liability by assigning his income to another party or entity. Therefore, to be able to shift income to someone else, that one must actually earn the income. This doctrine aims to against the tax evasion when the taxpayer tries to deflect income to another party. First, starting from the term “earning”, earnings can occur either through the direct efforts of the taxpayer or the taxpayer’s ownership of an asset that generates income. Based on that understanding about earning, there are 2 ways to shifting income from one to another: the transferee must really work to earn that income or share the ownership of an asset that creates income. For example, if you are an owner of a business and you want to shift one part of your income to your family member such as your son, you need to hire your son to work for your company and give him the pay rate that is appropriate with his job. And the other way is to share your investment income with him, same meaning with sharing your ownership with him. The assignment of income applies the “tree and fruit” metaphor, in which the fruits cannot be attributed to a different tree from that on which they grew. If you want to avoid the tax liability on the fruit from the tree, you must prove that the...

...Introduction to Programming with C# Variable Types & Initialising Variables Introduction to Variables A variable is a storage location that holds a value. You can think of a variable as a box in the computer’s memory holding temporary information. You must give each variable in a program an unambiguous name that uniquely identifies it in the context in which it is used. You use a variable’s name to refer to the value it holds. For example, if you want to store the value of the cost of an item in a store, you might create a variable simply called cost and store the item’s cost in this variable. Later on, if you refer to the cost variable, the value retrieved will be the item’s cost that you stored there earlier. Working with Primitive Data Types C# has a number of built-in types called primitive data types. The following table lists the most commonly used primitive data types in C# and the range of values that you can store in each. |Type |Description |Size (in bits) |Range | |int |Whole numbers |32 |-2147483648 to 2147483647 | |long |Whole numbers (larger range than int |64 |-9223372036854775808 to 9223372036854775807 | | |data type) | | | |float ...

...Assignment: Define CSS? -Cascading Style Sheets, a new feature being added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear. These style sheets can then be applied to any Web page. What are the three types of style in CSS? There are three types of CSS styles: * inline styles Inline styles are styles that are written directly in the tag on the document. Inline styles affect only the tag they are applied to. <a href="" style="text-decoration: none;"> ex. * embedded styles Embedded styles are styles that are embedded in the head of the document. Embedded styles affect only the tags on the page they are embedded in. ex. <style type="text/css"> p { color: #00f; } </style> * external styles External styles are styles that are written in a separate document and then attached to various Web documents. External style sheets can affect any document they are attached to. ex. <link rel="stylesheet" type="text/css" href="styles.css" /> Define JavaScript? -JavaScript is an interpreted programming or script language from Netscape. It is somewhat similar in capability to Microsoft'sVisual Basic, Sun's Tcl, the UNIX-derived Perl, and IBM'sREXX.

The children are our future and they need to be protected. When a person is looking to buy a future home they want to see a nice neighborhood that looks respectable and not as if it’s a bad neighborhood.

A power full asset of the computer is its ability to make decisions and to take alternate course of action based on the outcome. 2. What is a Boolean expression? a logical statement that is either TRUE or FALSE. 3 . Explain the purpose of comparison operators and logical operators. The purpose of a comparison operator is to test some kind of relationship between two entities examples are >, <, ==, !=, etc 4. How does a comparison performed on numeric data differ from a comparison performed on string data? There are commonly used interchangeably, and the distinction between them is a small one. Comparison to" should be used when comparison is made between specific people, things, or other instances. 5. How does Visual Basic compare the Text property of a text box? When you compare the Text property of a text box with another value the Text property behaves like a variant. Visual Basic compares one text box to another as strings and compares a text box to a numeric variable or constant with a numeric compare. You can force a numeric comparison on a Text property by using the Val function. 6 . Why would it be useful to include the ToUpper method in a comparison? When comparing strings, the case of the characters is important. An uppercase “Y” does not compare equal to a lowercase “y”. Since the user may type a name or word in either...

...Traffic Modeling Paper Concepts of math can be displayed and solved in many different ways. There are equations, graphs, and word problems and several concepts that can be used as examples to help solve mathematical issues. In week four of this College Algebra class Learning Team B was present with an assignment involving a traffic model. The traffic model is the key to helping Learning Team B solve the problems the assignment presents. The traffic model represents a number of cars within the area at any given time represented by letters. Learning team B must solve questions based on this model. There are several equations that were made in order to prove that the numbers of cars entering and leaving each intersection must be equal to keep traffic moving smoothly. Variables f and g are independent variables. This means that variables a through e are dependent on variables f and g. The number of cars at intersection a depends on how many cars turn from intersection f. The number of cars at intersection b depends on how many cars turn right from intersections f and g. This tells you that there are infinitely many solutions since the number of cars that turn onto Elm from Oak, Pine, and Aspen vary. Similarly the number of cars that turn onto Maple from Oak, Pine, and Aspen also vary. To list two acceptable traffic flows first let variable f be equal to 365 cars/hr and let variable g be equal to 400 cars/hr. Variable a would be equal to 850-365, which equals 485 cars/hr. Variable...
