Answer to Question #272025 in C++ for P11

Question

Implement a calculator using bitwise operators and for loops only. Your program should run correctly for positive integers only. You calculator should be able to perform following operations. Basic arithmetic functions (Addition, subtraction, division and multiplication); Square – to compute the square of the given value and Power – to compute the power of an integer. It should take two int arguments number and its power. Any operation that uses operators other than bitwise operators will be awarded zero marks

#include <iostream>
#include <math.h>
using namespace std;




void add(){
    int n1,n2;
    cout<<"\nEnter the first number: ";
    cin>>n1;

    cout<<"\n"<<n1<<" + "<<n2<<" : "<<(n1+n2);
}
void sub(){
    int n1,n2;
