C++ supports single line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.
C++ comments start with /* and end with */. For example:
/* This is a comment */
/* C++ comments can also
* span multiple lines
*/
A comment can also start with //, extending to the end of the line. For example:
#include<iostream>
usingnamespacestd;
main()
{
cout<<“Hello World”;// prints Hello World
return0;
}
