myLuckyNumber is indeed just the name of the variable, not the actual value itself. So 'int' is used to describe the type of the value.



Int here refers to the type of value stored. It doesn't matter that the name is in alphabets. ( If think about it, it would be quite hard remembering variable names if they all were numbers!! )
