Hi,

I'm a bit new to C's malloc function, but from what I know it should store the value in the heap, so you can reference it with a pointer from outside the original scope. I created a test program that is supposed to do this but I keep getting the value 0, after running the program. What am I doing wrong?

int f1(int * b) {
 b = malloc(sizeof(int));
 *b = 5;
}

int main() {
 int * a;
 f1(a);
 printf("%d\n", a);
 return 0;
}
