Trivial classes in C++

In this tutorial, we will be discussing a program to understand trivial classes in C++.

When a class/ struct contains explicitly defaulted value inside it, then it is known as Trivial classes. Further trivial classes have their own constructor, assignment operator and destructor.

Example

//using the default constructor struct Trivial {    int i;    private:    int j; }; //defining your own constructor //and then marking it as default struct Trivial2 {    int i;    Trivial2(int a, int b){       i = a;    }    Trivial2() = default; };

Output

(No output as we are just defining classes here and not creating object instances from them.)
