Just a Question
Given the following code fragment, I was asked to implement foo such that the program would output "America." How would you do it?

        int main()
        {
          char *p = "Hello";

          foo(         );
          printf("%s",p);

          return 0;
        }

My solution involved allocating new memory from the heap to store the new string, and changing p to point to that buffer. They didn't like that answer. They preferred the method of putting the new string in the data segment as well.

I personally would always avoid that, whenever possible. "Hello" is stored in a read-only area of memory as is "America" in their preferred solution. Any attempt to alter those strings will trigger a segfault. This is an accident waiting to happen.
