Comparing currency values as floats does not work

Question

If I type 0.01 or 0.02 the the program just exits immediately. What do I do?

#include 

char line[100];
float amount;

int main()
{
printf(\"E

Declare your comparative value as a float.

if (amount == 0.01f)
   printf("Quarters: 0\nDimes: 0\nNickels: 0\nPennies: 1");

Note that you could encounter some undefined behavior by directly testing float equality if you made some calculations with your float variable.
