Variable Scopes in C++

Variables in every programming language are used to store values that can change the program.

Integrating LibreOffice into C++

At our math website we publish printable PDF worksheets for school children. We’ve just started publishing crosswords, while relatively easy to create, they require much work to make them into tasks.
