    // variables that are made from class types are called objects
    // and a new object variable is called instance

    // by default class makes everything in it private that only its functions can access those variables
    // so if we want to access variables outsideof class we should make it public

// A class is private by default, however with struct everything is public and if we want sth in it private we should write private
// so class and struct are basically similar but you can have a style of using them
// for example you can use struct whenever you want to have a structure that has only variables or named plain old data like mathematical vector class
