How to use a class object in C++ as a function parameter

Question

I am not sure how to have a function that receives a class object as a parameter. Any help? Here is an example below.

#include

void function(cla         


        

Answer 1

At its simplest:

#include 
using namespace std;

class A {
   public:
     A( int x ) : n( x ){}
     void print() { cout << n << endl; }
   private:
     int n;
};

void func( A p ) {
   p.print();
}

int main () {
   A a;
   func ( a );
}

Of course, you should probably be using references to pass the object, but I suspect you haven't got to them yet.
