C program Quincy Compiler keeps Crashing after use of malloc

Hello, my quincy compiler compiles the program correctly, but it crashes as soon as I put my data in. Why might this be?

Code:

---

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

#define min(a,b) ((a) > (b) ? (b) : (a))
#define max(a,b) ((a) > (b) ? (a) : (b))

int main (void)

{


        int i, size;
        int *set;
        int max=0;
        int sum;
        float average=0;
        int min=max;

printf ("please give me the size\n");
scanf("%d", &size);

set = malloc(size *sizeof(int));

printf ("please give me the numbers\n");
scanf("%d", &set[i]);


free(set);
set=NULL

}

---

i is not initialized.


Quzah.

It looks like you forgot about a loop.

You should be getting several warnings, make sure you compile with the warnings set to max. Additionally, the minimum program in C is:

Code:

---

int main(void){

    return (0);
}

Or incremented, at any point. Even if by fluke i was in range it would always write to the same slot in the array.

Code:

---

i= 0;
printf ("please give me the numbers\n");

while (i++ < size)
  scanf("%d", &set[i]);
