Example 4-14

The following program determines an employee’s weekly wages. If the hours worked exceed 40, wages include overtime payment.

//Program: Weekly wages

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

double wages, rate, hours;

cout<<fixed<<showpoint<<setprecision(2); //Line 1

cout<<"Line 2: Enter working hours and rate: "; //Line 2

cin>>hours>>rate; //Line 3

if(hours > 40.0) //Line 4

wages = 40.0 * rate +

1.5 * rate * (hours - 40.0); //Line 5

else //Line 6

wages = hours * rate; //Line 7

cout<<endl; //Line 8

cout<<"Line 9: The wages are $"<< wages<<endl; //Line 9

return 0;

}

Sample Run In this sample run, the user input is shaded.

Line 2: Enter working hours and rate: 56.45 12.50

Line 9: The wages are $808.44

The statement at Line 1 sets the output of the floating-point numbers in a fixed decimal format, with a decimal point, trailing zeros, and two decimal places. The statement at Line 2 prompts the user to input the number of hours worked and the pay rate. The statement at Line 3 inputs these values into the variables hours and rate, respectively. The statement at Line 4 checks whether the value of the variable hours is greater than 40.0. If hours is greater than 40.0, then the wages are calculated by the statement at Line 5, which includes overtime payment. Otherwise, the wages are calculated by the statement at Line 7. The statement at Line 9 outputs the wages.
