CPP Comments

CPP comments are used to give a brief description about any specific line of code or about a module in the code to make the code more user-friendly.

CPP Comments can be of two types:

• Single line Comments
• Multi line Comments

Single Line Comments:

Single line comments can be used for commenting a line of the code or to write a single line description about the code. The lines starting with // is considered as single line comment.

Multi Line Comments:

Multi line comments can be used for commenting a part of the code or to write a multiple lines description about the code. The lines enclosed between /* */ are considered as multi line comments.

Example:

#include <iostream.h>
using namespace std;
 
int main()
{
int n;
cout << "Enter a number: ";
cin >> n;
 
/* if the number is less than 5,
the break will directly go to less label. */
if (n < 5)
goto less;
 
// otherwise print the number.
else
cout << n;
less:
cout << "less than 5";
return 0;
}

Output:

Enter a number: 4  
less than 5
