In this C program we will perform operations over Stack(i.e: Push Operation, Pop Operation and Display Operation). The Choice(i.e: Push,Pop or Display) will be made by the user and The Number will be taken from the user(i.e: For Push Operation).color>

input:

The Choice(i.e Push, Pop or Display) & The Number (integers) (i.e. for Push Operations) (15,10,128 etc.)

output:

The Operations will be excecuted as choosen by the user.

CODE---->

#include
#include
#define MAXSIZE 10
int s[MAXSIZE],top=-1;
void push(int x)
{
	if(top==MAXSIZE-1)
		printf("\n Stack Overflow.");
	else
	{
		top++;
		s[top]=x;
	}
}
void pop()
{
	int temp;
	if(top==-1)
		printf("\n Stack Underflow.");
	else
	{
		temp=s[top];
		printf("\n %d is Popped from Stack.",temp);
		top--;
	}
}
void display()
{
	int i;
	printf("\n The Stack Elements are...\n");
	if(top==-1)
	{
		printf("\n No Elements to display.");
	}
	else
	{
		for(i=top;i>=0;i--)
			printf(" %d ",s[i]);
	}
}
int main()
{
	int choice,x;
	while(1)
	{
		printf("\n1. Push\n2. Pop\n3. Display\n4. Exit");
		printf("\n Please, Enter your choice : ");
		scanf("%d",&choice);
		switch(choice)

					scanf("%d",&x);
					push(x);
