malloc() and free()

#include <stdlib.h>

int * b;

int main(void)
{
    int * a = NULL;
    a = (int *) malloc(sizeof(int));
    b = &a;
    free(b);
    return 0;
}

Would this result in a memory leak? If yes, why?

Once a process has ended, the kernel frees all the memory it allocated for it and that includes heap memory. Now go learn about memory management before making random assertions about the operating system you've been using for two weeks.
