// c# types are divided into 2 categories
// ValueType: int, float, enums, structs etc
// Ref types: interface, class…etc.
//ValueType are non nullable by default
// To make them nullable we use nullable
// type i.e ?
int x ;
int? y = null;
// using null coalesce operator ??
x = y ?? 0;
Console.WriteLine(x);

// To check the null value
// we use null coalesce operator ??
