How can i get the ASCII Value of the return key

Question

I woul like to check whether the user pushes the return key or not, and store it into a variable. How can I do that?

for example:

cin>>a;
if(a=='ASCII-Value of the return button') {continue your programm} ;

Or if there is any other possibility to check for the return button i would be thankful when you would share it with me.

Answer 1

Aditya told correctly. ASCII key of return is 13
just add 13 in the code

Answer 2

Thanks for the answers at both.
It is true what you said how to check a value but Sandeep understood my question better i think.
Because i wrote a small programm wich prints the Value of an ASCII sign. But now i wasn't able to insert the return key in my programm that it prints the ASCII value of the return button. (look my code for more information).

So 13 is the information needed =)
