Comments are text in your code that the C++ compiler completely ignores. They are used to explain what the code does, making it easier for you and others to read and maintain.
Single-line comments start with two forward slashes //. Any text between // and the end of the line is ignored.
// This is a single-line comment cout << "Hello World!"; // This prints Hello World to the screen
Multi-line comments start with /* and end with */. Any text between these markers will be ignored by the compiler.
/* This is a multi-line comment. It can span multiple lines. Very useful for long explanations. */ cout << "Hello World!";
Using comments effectively is a sign of a good programmer. Always write clear comments to describe complex logic!
