Question

A student wants to insert his name and school address in the C++ program that he has written. But this should not affect the compilation or execution of the program. How is it possible? Give an example.

Answer 1

He can use comments to write this information. In C++ comments are used to write information such as programmer’s name, address, objective of the codes etc. in between the actual codes. This is not the part of the programme. 

There are two types of comments. 

i) Single line (//) and 

ii) Multi line (/* and */)

i) Single line (//) : Comment is used to make a single line as a comment. It starts with //. 

Eg : //programme starts here.

ii) Multi line (/* and */): To make multiple lines as a comment. It starts with /* and ends with */. 

Eg : !* this programme is used to find sum of two numbers.*/
