Answer 2

1. You have pointer *p and regular variable with the same name, which is not allowed.
2. You have to allocate memory for your pointers, you can't access them randomly, so use malloc() function to allocate memory.
3. When you allocate memory, you have to free it, so use free() function at the end of your program, or whereever you want to free the memory.
4. You can't output stuff like "printf(q[i]);", you have to specify the type of variable, same as you did before
