Comment in C // C ++: Comment in C // C ++

The comment of the program is the explanation of the code writer in C / C ++ code, helping the reader, checking the source code is easier to understand. All programming languages have their own syntax for commenting.

C ++ supports single-line and multi-line comments. All characters in the comment are ignored by the C / C ++ compiler.

Comment in C / C ++ starts with / * and ends with * /. Below is an example of a single-line comment and multi-line comment in C ++:

 /* Day la mot comment don dong */ /* C/C++ cung ho tro cac comment * trai dai tren nhieu dong */ 

A comment can also start with //, extending to the end of the line. For instance,:

 #include using namespace std; main() { cout << "Hoc C/C++ co ban va nang cao"; // In dong chu Hoc C/C++ co ban va nang cao return 0; } 

When the above code is compiled, it will skip // Print C / C ++ and get high results and finally give the following result:

 Hoc C/C++ co ban va nang cao
