C++ Comments

This lesson is part of C++ · All levels

Summary

This lesson explains how to add comments to C++ code to make the program easier to understand. C++ provides one-line comments with // and block comments with /*... */. Commentary is completely ignored by the compiler, so it's only useful to humans who read code.

Key points

One line comment is written with //.
Multi-line block comments are written with /*... */.
The compiler ignores the comments so it does not affect the program's outcome.
Comments are useful to explain the intent of the code and temporarily disable the code.
