项目未编译，但Code :: Blocks中没有警告或错误

Question

I am going trough the book C Programming: A Modern Approach (KN King) and I am on chapter 2. I have done almost every exercise and program, but I have trouble with program #7.

Basically, it asks you to write a program that calculates the minimum amount of dollar bills you need for a specific amount. I have written the program and it works fine for bills of 20, 10, 5 and 1. But if I copy part of the code to use it for $50 bills, the file won't compile.

Here is my code:

int x, num, rest ;
printf("Insert amount to pay: ");
scanf("%d", &x);
printf("You will use the least amount of bills if you pay like so: \n");

num = x / 50;
rest = x - num * 50;
printf("$%d bills: %d\n", 50, num);

/*
num = rest / 20;
rest = rest - num * 20;
printf("$%d bills: %d\n", 20, num);
*/

num = rest / 10;
rest = rest - num * 10;
printf("$%d bills: %d\n", 10, num);

num = rest / 5;
rest = rest - num * 5;
printf("$%d bills: %d\n", 5, num);

num = rest;
printf("$%d bills: %d\n", 1, num);

return 0;

The program works perfectly, until I try to use the part I commented out (it is a copy of the other blocks, but with a number 20 instead of 10 for example).

The compiler gives no warnings or errors, it just won't compile. How do I fix this?

Answer 1

The solution to my problem was totally not C related as the code did in fact compile and try to run.

It turns out my antivirus blocked the .exe form running or something like that. I have no idea how and why in the world it would do it, but it did. As i disabled "Avast Free Antivirus" the code worked like a charm.

Thanks to Wather Vane for testing my code. You made me belive I didn't go insane yet :)
