How do i declare a variable in c++ : C++ Tutorial

3. Variable declaration In C++
Variables are the storage for data values, they are like rooms for storing data. Before using any variable, you must declare it and that is what is called variable declaration.

The following rules must be considered during variable declaration.
1. Variable name can not be keyword such as else, break, case, for and other keywords in C++. 2. Variable name can not contain space between it. For example, string first name is wrong variable declaration, it should be string firstname that is without space or it should contain underscore string first_name.
3. It should start with letter or underscore.
4. It should not contain special characters like $, @, £, # and other special characters.
