Things Not To Do with Stacks in C Programming

Popping from an empty stack can lead to undefined behavior. Always check if the stack is empty before popping.

Always check for stack overflow when pushing a new element onto the stack to prevent memory corruption.

Trying to pop from an empty stack is an underflow condition; always check the stack's size before popping.

Using a fixed-size stack can lead to overflow if not properly managed. Consider dynamic sizing with linked structures or realloc.

The 'top' variable should be initialized properly (usually to -1) to indicate an empty stack. Using it uninitialized can lead to unpredictable behavior.
