In this article, we shall learn how to get the class name using the C++ programming language.

Overview of Class in C++

In C++, everything is connected to classes and objects, each with its characteristics and procedures.

A class is a user-defined data type, which means you can create your types. It serves as an object constructor, sometimes known as a guideline, to generate new objects.

Get Class Name in C++

Let’s begin by importing the libraries so we can access all the methods necessary for our application.

#include <iostream>

We’ll create three classes and give them the names getClassNameSaad, getClassName, and className. In the following steps, we will get access to the names of these classes.

class getClassNameSaad {};

class getClassName {};

class className {};

Inside the main() function, we need to make an instance of the classes we have just created.

int main() {
  getClassNameSaad a_variable;
  getClassName b_variable;
  className c_variable;
}

Now that we are through with the previous step, we need to output the names of the classes. We will utilize the typeid() method, pass it the parameters a_variable, b_variable, and c_variable, and then access the name() function of the class.

std::cout << typeid(a_variable).name() << "\n";
std::cout << typeid(b_variable).name() << "\n";
std::cout << typeid(c_variable).name() << "\n";

Complete Source Code:

#include <iostream>

class getClassNameSaad {};
class getClassName {};
class className {};

int main() {
  getClassNameSaad a_variable;
  getClassName b_variable;
  className c_variable;

  std::cout << typeid(a_variable).name() << "\n";
  std::cout << typeid(b_variable).name() << "\n";
  std::cout << typeid(c_variable).name() << "\n";
  return 0;
}

Output:

16getClassNameSaad
12getClassName
9className

The integer numbers in the output before each class’s name represent the total number of letters included in that class’s name.
