Q. Push,Pop and Traversing using array in Stack ?

THE OUTPUT WOULD BE

     #include<stdio.h>
#include<conio.h>
void main()
{ clrscr();
int x,a[7],top=-1,item,i;
while(x!=4)
{ printf("Enter choice:");
 printf("\n1.Push\n2.Pop\n3.Traversing\n4.Exit\n");
 scanf("%d",&x);
 switch(x)
 { case 1: printf("Enter element for insert=");
   scanf("%d",&item);
   top=top+1;
   if(top!=8)
   { a[top]=item;
     printf("Element successfully inserted\n");
   }
   else
   printf("Stack is full\n");
   break;
   case 2: if(top==-1)
   printf("Stack is empty\n");
   else
   { item=a[top];
     top=top-1;
     printf("Element deleted %d\n",item);
   }
   break;
   case 3: if(top==-1)
   printf("Stack is empty\n");
   else
   { printf("Stack elements are\n");
     for(i=0;i<=top;i++)
     printf("%d\t",a[i]);
   }
   printf("\n");
   break;
   case 4: break;
  default: printf("Wrong choice\n");
   break;
 }
}
getch();
}
