C Passing an int in a function?

Question

I am getting incorrect results when passing a int in a function:

int recruit(int var1, int re_unit, char *char_buffer, int var2) {
 int run = 1;
 int int_buffer          


        

Answer 1

Uninitialized values in C's functions are not 0, they are just garbage whatever memory had at that particular moment..

#include <stdio.h>
int main()
{
    int a;
    printf("%i\n", a);
    return 0;
}

That should demonstrate the idea...

Hopefully I interpreted the question correctly.

Please change this statement int recruit(int lvl, int re_unit, char *char_buffer, int u_lvl, int lvl2) to int recruit(int lvl, int re_unit, char *char_buffer, int lvl, int lvl2). You are observing an incorrect value due to uninitialized variables.
