Thread: Weird return statement. Not exactly sure what it means. Can someone explain this?

Can someone explain what this return call is doing? This is an int isEmpty function that involves stacks.

Code:

int isEmpty( stack* myStack ){
return mystack->front == NULL;
}

Is this some some sort of conditional statement combined with a return call?

"myStack points to a "stack" struct. The pointer, "front" is a member of that struct. If "front" is set to "NULL" then it does not point to anything. The stack is empty, and the function returns a non-zero value (true). If "front" DID point to a valid address, then the function would return zero (false).

The statement is not weird at all! You need to study more about both pointers and structs to understand this better.
