\a ?

[MatieA]

My instructor gave us some sample code and she used a \a
Can someone tell me what it is used for? I can't find it online or in my textbook?

cout <<"This program processed "<<counter<<" numbers."<<endl;
	 cout <<"The total value of the numbers is "<<totValue<<"\a \n\n";

'\a' is the escape character for a beep ( a = alert )

All Escape Character have its importance in C++.
I am sending u some common Escape characters.

\a = alarm or alert
\b = it is used for backspace.
\t = it is used for tab(long space)
\n = it is used for new line.
\f = it is used for form feed.
\r = it is used for return to the start of the same line.
\\ = it is used to print one back slash.
\" = it is used to print the inverted commas.

All these escape characters will be used in double commas.


I think just reading them is not sufficient. you should make practice of all these urself atleast once than all will be clear.
Thanks

There should be a few more than those:
\' = single quote
\v = vertical tab
\? = '?'
\ (octal number) and
\x (hexadecimal number) = corresponding ASCII character
\ (newline) = the string continues on the line below

all of those can be used both in single quotes and double quotes
