C Stack

[cap10Ibraim]

I have this question
Add to the "stack.c" an interface function void multipop(int k) that pops k elements from the stack, or until the stack is empty

I can solve it but I changed the prototype to include the name of the stack? How is it possible to do it and stick to this prototype given ?!

What's stack.c?

And doesn't pop normally return the value. So multi-pop should surely return multiple values? What your describing should be called something more like a delete.

Are you talking about THE stack or just any stack? If its just any stack and it's C then you will need to give it some sort of pointer to the data structure.

yes that's what I did but I should stick to the prototype given which is void multipop(int k)

[dwhitney67]

The only way to adhere to the prototype you describe is to declare your stack object as a global variable, and frankly that would be silly. After all, this would preclude an application from supporting multiple stacks.

The approach you have taken, of passing the pointer of a stack to the function, is the best solution (for C).

Thanks for the support guys ):P
