Thread: codes keeps crashing with random (BEGINNER)

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


#define THREE 3
int main (void)
{
    int check = 0;
    int first_number = rand() % 101;
    int second_number = rand() % 101;
    int third_number = rand() % 101;
    
    while(check != THREE)
    {
        if (first_number % 2 == 0 || second_number % 2 == 0 || third_number % 2 == 0)
        {
            check++;
        }
        if (first_number % 2 != 0 || second_number % 2 != 0 || third_number % 2 != 0)
        {
            check++;
        }
        if (first_number > 50 || second_number > 50 || third_number > 50)
        {
            check++;
        }
        else
        {
            check = 0;
        }
    }
    if (check == THREE)
    {
        printf("%d %d %d",first_number,second_number,third_number);
    }
    else
    {
        srand (time(NULL));
        printf("NOTHING");
    }
    return 0;


}

Like I wrote in the title im a beginner and I NEED HELP, so my problem is the code keeps crushing and i dont understand why.

I am thankful for any kind of help/explanation.

First, I agree with @GReaper. I think you need to work out what you are trying to do on paper BEFORE coding.

You are also running srand() at the end of the run. It is meaningless at this point. You should run srand() BEFORE any call to rand().
