In C I have never really used malloc to alloc memory from the
heap. Now when using C's data types you are using the stack if
I am correct. In programming requirements are there times when
you want memory allocated from either parts of memory?

int mem[100]; 100 ints from stack
int *pi=malloc(100); 100 ints from heap

Obviously?

Suppose you want to return an array from a method? If the method
allocates the array on the stack then it won't be valid after
the method returns.

Don't confuse him. Bill uses C, which doesn't have C++ methods.

In addition "pi = malloc(100);" returns storage for 100 chars, not
ints. To get 100 items use the normal malloc call of "pi =
malloc(100 * sizeof *pi);", which will follow the type of pi.
