Difference between Class variable, Member variable, and Local variable, Global Variable [closed]

Answer 1

a variable defined static in class definition is class variable.

public MyClass
{
    static int a; // class variable
}

a variable declared in a function (Method) is local variable.

public class MyClass
{
    static void Main()
    {
        string name; //local variable
    }
}

a variable declared in a class definition, and when class is instantiated and those variables will be member variable

public class MyClass
{
    int a; // here they are local variable of class body.
    int b;
}

//create instance of class

MyClass mc = new MyClass();
mc.a = 10; //these are member variables
mc.b = 11;
