hi guys, i have a few questions which is actually my assignments, but i'm still confuse about stack and implementations using pointers in C. this is the questions:
1. write a function to find if the stack is empty or not.
2. write a function to find the number of elements present in a stack.
3. write a function to display the top most element and the element at the bottom of the stack.
4. write a function to find the sum of elements in the stack.
