Is it possible to know the object instance name / variable name from within a class method? For example:
#include <iostream>
using namespace std;
class Foo {
public:
void Print();
};
void Foo::Print() {
// what should be ????????? below ?
// cout << "Instance name = " << ?????????;
}
int main() {
Foo a, b;
a.Print();
b.Print();
return 0;
}
Not with the language itself, but you could code something like:
#include <iostream>
#include <string>
class Foo
{
public:
Foo(const std::string& name) { m_name = name;}
void Print() { std::cout << "Instance name = " << m_name << std::endl; }
private:
std::string m_name;
};
int main()
{
Foo a("a");
Foo b("b");
a.Print();
b.Print();
return 0;
}
