Two colons (::) are used in C++ as a scope resolution operator. This operator gives you more freedom in naming your variables by letting you distinguish between variables with the same name. For example, MyFile::Read refers to the Read method of the MyFile class of objects, as opposed ...
An identifier has block scope if its corresponding declaration appears inside a block (parameter declaration in function definition apply). The scope ends at the end of the corresponding block.No different entities with the same identifier can have the same scope, but scopes may overlap...

Variables declared inside blocks of code are only accessible by the code between the curly braces, which follows the line in which the variable was declared: Example publicclassMain{publicstaticvoidmain(String[]args){// Code here CANNOT use x{// This is a block// Code here CANNOT use xin...
