This is a basic array based implementation of stack data structure in C.
// Stack - Array based implementation.
// Creating a stack of integers.
#include<stdio.h>
#define MAX_SIZE 101
int A[MAX_SIZE]; // integer array to store the stack
int top = -1; // variable to mark top of stack in array
// Push operation to insert an element on top of stack.
/*
Evaluation Of postfix Expression in C++
Input Postfix expression must be in a desired format.
Operands must be integers and there should be space in between two operands.
Only '+' , '-' , '*' and '/' operators are expected.
