What .NET Developers Must Know about C++ Classes: Listing 2
An assignment between two C++ objects.
#include <iostream>
using namespace std;
class MyClass {
public:
MyClass(const int fieldInitValue) : myField_{fieldInitValue} {}
int GetField() { return myField_; } const
void SetField(const int value) { myField_ = value; }
private:
int myField_;
};
// pay attention to the ending semicolon in class declarations like
// above. It can't be ommitted in C++.
int main(int argc, char* argv[]) {
MyClass my1 { 5 }, my2 { my1 };
// my1 and my2 are (don't refer to) different instances
my2.SetField(3);
// my1 prints "5"; my2 does "3"
cout << "my1.MyField = " << my1.GetField() << ", my2.MyField = " << my2.GetField() << endl;
}
