Programming Challenge #6: ANNUAL PAY | Starting Out With C++ | Chapter 2

Programming Challenge #6: ANNUAL PAY | Starting Out With C++ | Chapter 2 comes from the “Review Questions and Exercises” section at the end of Chapter 2 in Tony Gaddis’ book Starting Out With C++ : From Control Structures Through Objects/8th Edition.

>_ The Problem

/********************************************************************
* Suppose an employee gets paid every two weeks and earns $2,200
* each pay period. In a year the employee gets paid 26 times.
* Write a program that defines the following variables:
*
* payAmount - 2200.0.
* payPeriods - 26.
* annualPay - to be calculated.
*
* The program should calculate the employee's total annual pay by
* multiplying the employee's pay amount by the number of pay
* periods in a year and store the result in the annualPay variable.
* Display the total annual pay on the screen.
********************************************************************/

>_ The Solution

#include <iostream>
using namespace std;
int main()
{
    double payAmount = 2200.0,
           payPeriods = 26,
           annualPay = payAmount * payPeriods;

    cout << endl << endl;
    cout << "Total annual pay = $" << annualPay;
    cout << endl << endl;

    return 0;
}

>_ Topics Used:

2.1  The Parts of a C++ Program

CONCEPT: C++ programs have parts and components that serve specific purposes.

2.2  The cout Object

CONCEPT: Use the cout object to display information on the computer’s screen.

2.3  The #include Directive

CONCEPT: The #include directive causes the contents of another file to be inserted into the program.

2.4  Variables and Literals

CONCEPT: Variables represent storage locations in the computer’s memory. Literals are constant values that are assigned to variables.

2.5  Identifiers

CONCEPT: Choose variable names that indicate what the variables are used for.

2.9  Floating-Point Data Types

CONCEPT: Floating-point data types are used to define variables that can hold real
numbers.

2.12 Variable Assignments and Initialization

CONCEPT: An assignment operation assigns, or copies, a value into a variable. When a value is assigned to a variable as part of the variable’s definition, it is called an initialization.

2.13 Scope

CONCEPT: A variable’s scope is the part of the program that has access to the variable.

2.14 Arithmetic Operators

CONCEPT: There are many operators for manipulating numeric values and performing arithmetic operations.

2.17 Programming Style

CONCEPT: Programming style refers to the way a programmer uses identifiers, spaces, tabs, blank lines, and punctuation characters to visually arrange a program’s source code. These are some, but not all, of the elements of programming style.
