So these are the generic steps to initialize variables. But these initialization plays a major role because for large projects a single module will not be handled by a single individual so it must be generic that every one in the team should understand for what purpose a particular variable has been declared by just reading its name itself. Many new developers do not concentrate on prefixes of the variable declarations.
