C++ difference between '//' and '///' [duplicate]

Question

Why in Code::Blocks at least '///' is dark blue and '//' is blue? and i have seen in some source codes that sometimes they use '///' and other times '//'.

Answer 1

It means nothing to C++, its the same as the traditional //. The /// is typically used for documentation. For codeblocks, it triggers a highlighting mode for Doxygen..

// Normal comment
/// Doxygen comment
//! Doxygen comment

/*! Doxygen comment block */

Answer 2

For the C++ compiler both are just comments.

But, source code documentation tools like doxygen might handle them in different ways.

Example:

• /// -> special comment block, eg: function documentation
• // -> standard comment

/// tells doxygen that this comment shall be part of the generated documentation.
