Thread: Getting error on Matrix

Hello there. I've a problem. I've a code and it works on my linux laptop; however it doesnt work on a matrix server. Im getting error

Code:

 
file.c: In function ‘CondCheck’:file.c:40:3: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]

The code of the programme

Code:

#include <stdio.h>

    {
        
        if(bina>=co) 
        {
            printf("1");

Im just a begginer. What I should do to solve this error?

Fixed it! I changed the code to

Code:

/*THE CONDTION*/
int CondCheck (int error)
{
    while (error < 0 || error >= 2147483647)
    {
        printf("\n*** This number is not a valid number, try again ***");
        scanf("%d", &error);
    }
}
