Help I am stuck on c++ creating classes please help me!

Question

#include <iostream>
using namespace std;

class Number
{
private:
int num;
public:
Number(int n) {
num = n;
}
//complete the method
int square() {

};
};

int main() {
int x;
cin >> x;
const Number myNum(x);
cout << myNum.square();
}

Answer 1

Because you defined <myNum> as a const object, you need to also specify member function square() as const by adding `const` after the parameter parentheses.

int square() const
{
// function body here ...
}

In that function also, you need to return member data <num> multiplied by itself.

Answer 2

Hi Ipang, I follow your instruction to write the code as below:

int square() const{
return (n*n);
}

But it says n was not declared. Please help.

Answer 3

Chin Eu,
I made a typo then, it should be referring to private member <num> instead of <n>.

Thank you for correcting me ... : )

Answer 4
