Where do you call the function Tax()? Certainly, no where.

Here's an example of how it works

``````#include <stdio.h>

int special_function(); /* Here is my card, call me if you need me */

int main (void) /* notice that it is not void main */
{
int mywallet …``````

I answered this question for you, in the other forum.

Now that you're cross posting, I won't bother henceforth. You're wasting our time.

I answered this question for you, in the other forum.

Now that you're cross posting, I won't bother henceforth. You're wasting our time.

I didn't even know there was something wrong with cross posting and i came over here because after a while no one was responding to my posts, so sorry if i offended u in any way.
I carried over minutes_max , hours_max and vehicle and it runs now but it crashes when i input the last variable for the main() part of the program
