In this tutorial you will learn about the C++ Comments and its application with practical example.
C++ Comments
C++ Comments are a set of statements that are not executed by the C++ compiler. The use of comments makes it easy for humans to understand the source code. Usually comments gives you inside or explanation about the variable, method, class or any statement that exists in source code. The comment statements are ignored during the execution of the program.
C++ Single-line Comments:-
A ‘//’ (double forward slash) is used to specify a single line comment, which extends up to the newline character.

#include <iostream> using namespace std; int main() { cout<<"Hello World!"; // It prints Hello, World! return 0; } |
Output:-
|
1 |
Hello World! |
C++ Multi-line Comments:-
If you want to comment multiple lines then you can do it using /* and */, everything in between from /* to */ is ignored by the compiler-
|
1 2 3 4 5 6 7 8 9 10 11 |
#include <iostream> using namespace std; int main() { /* It prints Hello World! */ cout<<"Hello World!"; return 0; } |
Output:-
|

Hello World! |
