Program Of Stack in C-Language

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).

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.

void push(int x)
{

  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");

 {
  printf("\n No Elements to display.");
