Question

Please write a C++ code for 2D matrix by using STACK push and pop function.

Answer 1

Below is the code:

#include<bits/stdc++.h>
  
using namespace std;
#define MAX_SIZE 1000
class Stack
{
int top;
public:
int a[MAX_SIZE];   
  
Stack() { top = -1; }
bool push(int x);
int pop();
};
  
bool Stack::push(int x)
{
if (top >= (MAX_SIZE-1)) {
cout << "Overflow";
return false;
}
else{
a[++top] = x;
cout<<x <<" added to stack ";
return true;
}
}
  
int Stack::pop() {
if (top < 0)
{
cout << "Underflow";
return 0;
}
else
{
int x = a[top--];
return x;
}
}
  
int main() {
class Stack s;
s.push(10);
s.push(20);
s.push(30);
cout<<s.pop() << " removed from stack ";
  
return 0;
}

Output
