Hi,

If a function is returning a pointer and if that pointer was returned by a malloc function , how do I free that pointer ? If I run valgrind , it will show memory leak since "k" was not freed. How do I free "k" in following ?

Example:

int * sum(int a, int b)
{
int sum;
int *k=malloc(sizeof(int));
sum=a+b;
k=∑
return k;
}

Thank you.
