A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. Below is a C program to implement a stack using an array, supporting push, pop, and display operations.
Code Example
#include <stdio.h>#include <stdlib.h>#define MAX 5 // Maximum size of the stackint stack[MAX];int top = -1; // Initialize stack as empty// Function prototypesvoid push();void pop();void display();int main() {int choice;while (1) {printf("\n*** Stack Menu ***\n");printf("1. Push\n");printf("2. Pop\n");printf("3. Display\n");printf("4. Exit\n");printf("Enter your choice: ");scanf("%d", &choice);switch (choice) {case 1:push();break;case 2:pop();break;case 3:display();break;case 4:exit(0);default:printf("Invalid choice! Please try again.\n");}}return 0;}// Function to push an element onto the stackvoid push() {int val;if (top == MAX - 1) {printf("Stack Overflow! Cannot add more elements.\n");} else {printf("Enter the element to push: ");scanf("%d", &val);stack[++top] = val;printf("Element pushed: %d\n", val);}}// Function to pop an element from the stackvoid pop() {if (top == -1) {printf("Stack Underflow! The stack is empty.\n");} else {printf("Element popped: %d\n", stack[top--]);}}// Function to display the elements of the stackvoid display() {if (top == -1) {printf("Stack is empty!\n");} else {printf("Stack elements:\n");for (int i = top; i >= 0; i--) {printf("%d\n", stack[i]);}}}Copied!✕Copy Build an Array With Stack Operations - LeetCode
