C++ Comments

Comments are text in your code that is ignored by the compiler. They are used to explain code, make it more readable, or prevent execution when testing alternative implementations.

Using comments is invalid in the compiled executable but crucial for source code maintenance.

Single-line Comments

Single-line comments start with two forward slashes (//). Any text between // and the end of the line is ignored.

Multi-line Comments

Multi-line comments start with /* and end with */. Any text between them will be ignored. These are excellent for longer explanations or commenting out blocks of code.
