Question

Write a C++ console application that uses functions to calculate an employee’s salary.

PART 1: Create a void function to print a menu asking the user to choose from the following options:

1 - Annual salary

2 - Monthly salary

3 - Daily rate of pay

4 – Exit

The void function only prints the menu. Format your cout statement to include the menu as displayed above.

If the chosen option is 1- Annual Salary, ask the user for the number of hours they work perweek and their hourly wage:

Annual Salary = hourly wage x hours worked per week x 52

If the chosen option is 2- Monthly Salary, ask the user for the number of hours they work perweek and their hourly wage:

Monthly Salary = Annual Salary / 12

If the chosen option is 3- Daily Rate of Pay, ask the user for the number of hours they work perday and their hourly wage:

Daily Rate of Pay = hours worked in a day x hourly wage

PART 2: Create different double functions to calculate each of these rates.

Continue to prompt the user for a value until an invalid option is entered. The sentinel value in this application is 4 (Exit). An invalid option would be anything other than 1,2,3, and 4. Output the information back to the user in columns with one column including labels and the other including a value. Be sure to include the units for the values printed to the screen. Format any real numbers to two decimal places.

Answer 1

#include
using namespace std;

void menu() //menu function
{
//creating menu for the user
cout<<"1 - Annual salary"< cout<<"2 - Monthly salary"< cout<<"3 - Daily rate of pay"< cout<<"4 – Exit"< }
double annual() //annual salary calculation
{
double sal,hr,wg; //variable declaration
//accepting values from user
cout<<"Number of hours worked per week"< cin>>hr;
cout<<"Hourly wage"< cin>>wg;
sal= (wg * hr * 52);
return sal; //returning the result
}
double month() //monthly salary calculation
{
double sal,hr,wg; //variable declaration
//accepting values from the user
cout<<"Number of hours worked per week"< cin>>hr;
cout<<"Hourly wage"< cin>>wg;
sal= (wg * hr * 52)/12;
return sal; //returning the result
}
double day() //per day salary calculation
{

//accepting values from the user
cout<<"Number of hours worked per day"< cin>>hr;
cout<<"Hourly wage"< cin>>wg;

return sal; //returning the result
}
int main()
{
int ch; //variable declaration
double res=0.0;
do{

cout<<"Enter your choice "< cin>>ch;
switch(ch)
{
case 1:
res=annual(); //calling the annual function
cout<<"The Annual Wage : "< break;
case 2:
res=month(); //calling the month function
cout<<"The Monthly Wage : "< break;
case 3:
res=day(); //calling the day function
cout<<"The Daily Wage : "< break;
case 4:
exit(0); //system exit
default:
cout<<"Invalid Choice"< break;
}
}while(ch!=4);
return 0;
}
