Implementation in C:
#include<stdio.h>

#define N 5
int stack[N];
int top=-1;

void push()
{
int x;
printf("Enter data:");
scanf("%d", &x);
if(top==N-1)
{
printf("Overflow");
}
else
{
top++;
stack[top]=x;
}
}

void pop()
{
int item;
if(top==-1)
{
printf("Underflow");
}
else
{
item=stack[top];
top--;
}
printf("%d\n", item);
}

void peek()
{
if(top==-1)
{
printf("Stack is empty");
}
else
{
printf("%d\n", stack[top]);
}
}

void display()
{
int i;
for(i=top;i>=0;i--)
{
printf("%d\t", stack[i]);
}
}

void main()
{
int ch;

do
{
printf("Enter choice for operation: ");
scanf("%d", &ch);
switch(ch)
{
case 1:
push();
break;
case 2:
pop();
break;
case 3:
peek();
break;
case 4:
display();
break;
default:
printf("Invalid choice");
}
}while(ch!=0);

}

Ma'am, you are one of the best teachers I've ever known. You've made it so easy for me to understand all the stuffs that my school teacher made so difficult. Thank you so much ma'am.

Hi Jayanti ma'am now you are like a GOD for so many of the Students, because in our India @ Degree Colleges so many of the Professors themselves they will not be knowing even the BASIC CONCEPTS also, only few Professors like you will be Excellent..We need Professors like you @ clgs..Love you ma'am as your Student😘😘😍

I am very lucky to find this video and having you as my teacher.

[Jyo-gogj]

mam, a standing salute for the effort you put into these videos, your teaching is simply amazing, even after 4 years people are relying on your videos, because no matter in which colleges we are, lecturers now a days don't take the burden of making things clear, and they expect us to understand everything without explaining what actually happens there....thank you from the bottom of my heart for the lectures mam ❤

[anjalityagi]

Mam you are really a blessing for me in this pandemic.... when I need a teacher as like you....you resolve all my problems....
Thankyou so
