Please uhm what is the use of multi-line comment in c++....how and when will i use it

Answer 1

If you want to comment a huge block of text or code.
It's easier to just type /* in the beginning and */ at the end of such a block than having // in front of every line.
However most editors support a shortcut to comment multiple selected lines using //

Answer 2

// This is a single-line comment in C++.

// This is a really long comment
// that is very long and can span
// multiple lines.

/* C++ supports comments
like this */ (newline is ignored)

/*
* This is a prettier version of
* this style of comment (aka
* a C-style comment).
* The *s on the begining of
* each line are cosmetic-only.
*/
