Hello folks, can someone resolve this seg fault with me please, i can't find the error where it occur. Thank you.

#include <stdlib.h>
 #include <stdio.h>
 int ft_ultimate_range(int **range, int min, int max)
 {
    int lentgh;
    int i;
    int mi;
    
    mi = min;
    lentgh = max - min;
    if (min >= max)
    {
        // *range = NULL;
        return (0);
    }
    *range = malloc(sizeof(int) * lentgh);
    if(!range)
    {
        return 0;
    }
    i = 0;
    while (min < max)
    {
        range[0][i] = mi;
        i++;
        mi++;
    }
    return (i);
}

int main()
 {
    int i = 0;
    int min = 5;
    int max = 19;
    int **range = 0;
    int ptr = ft_ultimate_range(range, min, max);`

    while(i < max - min)
    {
        printf("%d\n", ptr);
        i++;
    }
    return (0);
}

What does the debugger tell you?
Canina‭ wrote over 3 years ago

This looks like a homework exercise. A large part of what those are about is to familiarize you with various concepts. In this case, you have a problem, so aside from simply implementing the specified functionality, you also need to debug your code to figure out what's wrong with it. Therefore: please edit your question to show what you have tried in order to solve this on your own, and what the results of those efforts were; including what you have tried, and found, with a debugger.
