Exercise 2.4 Calculating average hourly pay rate

 #include <stdio.h>
 int main (void)
 {
     double pay = 0.0;
     double hours = 0.0;
     int dollars = 0;
     int cents = 0;

     //ger the weekly pay
     printf ("Enter your weekly pay in the dollars:");
     scanf ("%lf", pay);

     //get the weekly hours
     printf ("Enter your hours worked");
     scanf ("%lf", hours);

     //calculate the average hourly rate -dollars first
     dollars = (int)(pay)/(hours);

     //get the cents ：subtract the dollars from the hours rate and then multiply by 100 to get the cents
     // If we then add 0.5 and convert the result back to an integer , it will be th nearest cent.
     cents = (int)(100*(pay/hours - dollars) + 0.5);

     //output the average houly rate
     printf ("%d dollars %d cents", dollars, cents) ;
     return 0;
