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.
void Push(int x)
{
if(top == MAX_SIZE -1) { // overflow case.
printf("Error: stack overflow\n");
return;
}
A[++top] = x;
}
// Pop operation to remove an element from top of stack.
void Pop()
{
if(top == -1) { // If stack is empty, pop should throw error.
printf("Error: No element to pop\n");
return;
}
top--;
}
// Top operation to return element at top of stack.
int Top()
{
return A[top];
}
// This function will return 1 (true) if stack is empty, 0 (false) otherwise
int IsEmpty()
{
if(top == -1) return 1;
return 0;
}
// This function is just to test the implementation of stack.
// This will print all the elements in the stack at any stage.
void Print() {
int i;
printf("Stack: ");
for(i = 0;i<=top;i++)
printf("%d ",A[i]);
printf("\n");
}
int main() {
// Code to test the implementation.
// calling Print() after each push or pop to see the state of stack.
Push(2);Print();
Push(5);Print();
Push(10);Print();
Pop();Print();
Push(12);Print();
