This is an example of using default parameters.

The function will accept up to 2 parameters and calculate a gross pay

The function header is similar to

float calcGrossPay(float hours, float rate)

return hours * rate

if there is no rate in the function call, the pay rate defaults to $8.75

if no hours are in the function call, the hours defaults to 20 hours

call the function three times to ensure the function works

1. calcGrossPay()
2. calcGrossPay(hours, rate)
3. calcGrossPay(hours)

float calcGrossPay(float hours=20 float rate=8.75)

{

return hours * rate

}

Output is from main

calcGrossPay( )

oputput should be hours are ?????.??

rate is ?????.??

gross pay is ?????.??

calcGrossPay(5, 3.33)

oputput should be hours are 5.00

rate is 3.33

gross pay is 16.65

calcGrossPay(5)

oputput should be hours are 5.00

rate is 8.75

gross pay is 43.75

call the function three times to ensure the function works
