1. Write a C program to construct a stack of integers and to perform the following operations on it: Push b. Pop c. Display The program should print appropriate messages for stack overflow and stack underflow. #include<stdio.h> int stack[10],choice,n,top,x,i; void push(void); void pop(void); void display(void); int main() { top=-1; printf("\n Enter the size of STACK[MAX=10]:"); scanf("%d",&n); printf("\n\t STACK OPERATIONS USING ARRAY"); printf("\n\t--------------------------------"); printf("\n\t 1.PUSH\n\t 2.POP\n\t 3.DISPLAY\n\t 4.EXIT"); do { printf("\n Enter the Choice:"); scanf("%d",&choice); switch(choice) { case 1: { push(); break; } case 2: { pop(); break; } case 3: { display(); break; } case 4: { printf("\n\t EXIT POINT "); break; } default: { printf ("\n\t Please Enter a Valid Choice(1/2/3/4)"); } } } while(choice!=4); return 0; } void push() { if(top>=n-1) { printf(...
