How do I access the data of an object with an object of the same class?

[dkjdod]

I'm just starting to use objects. I cannot figure out how to pass data between objects. Here is what I have:

#include <iostream>
#include <sstream>
#include <stdexcept>
using namespace std;

class IntMoo{
private:
int number;
    
public:
IntMoo{
number=1;    
}

Intmoo add(const IntMoo& n) const{
IntMoo whatever;    
whatever.number = (n.number+number);
return whatever;}
};

int main () {
IntMoo random(1), name(1);
random.add(name);
return 0;}

Your parameter is "IntMod" not "IntMoo". Is that your problem?

There is some other problem.

I added in the rest of the program (well, this is not the program I have to turn in. It is a very simplified version).

Another question:

When I change data in an object then return to the main, does the data in the object stay changed?

How does my add function pass the value of n with "&" if n is a constant (my instructor requires the line "Intmoo add(const IntMoo& n) const"?
