Do everything in pennies... $1000.00 is simply 100,000 pennies.
Code:
// inputs
int InputAsPennies( void )
{ float x;
printf("Enter amount : $ ");
scanf("%f",&x);
return (int) x * 100); }
// display dollars
void DisplayAsDollars(int Amount)
{ printf("$ %d.%d", Amount / 100, Amount % 100); }
Easy enough?
