Answer 1

#include <iostream>
using namespace std;
int arr[100], x=100, top=-1;
void push(int item) {
   if(top>=x-1)
   cout<<"Stack Overflow"<<endl;

      top++;
      arr[top]=item;
   }
}
void pop() {
   if(top<=-1)
   cout<<"Empty stack"<<endl;
   else {
      cout<<"Removed element is "<< arr[top] <<endl;
      top--;
   }
}
void show() {
   if(top>=0) {
      cout<<"Stack Contents:";
      for(int i=top; i>=0; i--)
      cout<<arr[i]<<" ";
      cout<<endl;
   } else
   cout<<"No element in the stack";
}
int main() {
   int choice, item;
   cout<<"1) Insert into the stack"<<endl;
   cout<<"2) Remove item from the stack"<<endl;
   cout<<"3) Display contents of the stack stack"<<endl;
   cout<<"4) Exit"<<endl;
   do {
      cout<<"Enter an option: "<<endl;
      cin>>choice;
      switch(choice) {
         case 1: {
            cout<<"Enter a number to insert"<<endl;
            cin>>item;
            push(item);
            break;
