Why nonstatic data initialization is important

by okanakyuz · 2 March 2020

Before Modern C++ approach (C++11) we initialized our class something like that.

#include <iostream>

class MyClass {
    int data1;
    int data2;
public:
    MyClass(){
        this->data1 = 0;
        this->data2 = 0;
    }
};

#include <iostream>

class MyClass {

int data1;

int data2;

public:

MyClass(){

this->data1 = 0;

this->data2 = 0;

}

};

But Modern C++ brings us this option.

#include <iostream>

class MyClass {
    int data1 {0};
    int data2 {0};
public:
    MyClass(){
        //other codes
    }
};

#include <iostream>

class MyClass {

int data1 {0};

int data2 {0};

public:

MyClass(){

//other codes

}

};

Initializing by using simple curly brackets creates a method which runs before everything includes constructor methods, as a result, we don’t have to do anything for other alternative constructors.
