Experiment 1

The document contains a C program that implements stack operations using an array, allowing users to push, pop, and display elements in the stack. It includes a menu-driven interface for user interaction and handles overflow and underflow conditions. The program successfully executes a series of stack operations based on user input until the exit option is selected.
