Explanation / Answer
Hi
I have updated the code and highlighted the code changes below
#include <stdio.h>
#define AFTERTAX 1.056
int main()
{
double beforet, aftert;
int dollars, cents;
printf("Enter the price of your item.");
scanf("%lf" ,&beforet);
aftert = beforet*AFTERTAX;
dollars = aftert;
cents = (aftert-beforet) * 100;
printf("The price of your item is %.2lf. "
"The price of your item plus tax is %d dollars and %d cents. ",
beforet, dollars, cents);
getchar();
return 0;
}
Output:
sh-4.2$ gcc -o main *.c
sh-4.2$ main
Enter the price of your item.900
The price of your item is 900.00.
The price of your item plus tax is 950 dollars and 5040 cents.
