Answer 2

use the constructor method.

#include <iostream>
using namespace std;

class MyClass{
public:
int value;

//This is the constructor, it has the class name, is public and doesn't have a return type.
MyClass(int val){
value=val;
//or this->value=val;
}
};

int main() {
MyClass object(5);
cout<<object.value;
return 0;
}
