Is askNumber() part of C++ Functions?

[OldFangle]

Hi
I'm seeing askNumber() in many instances but I can't trace it back to a clear-cut definition or locate it in a Glossary or reference list. I can't find it through Searches here or in Google or other places, except where it's mentioned within Code. There's no direct listing, definition, or full explanation of it.
If it is a member of a Class, to which Class does it belong?
What Glossary of Terms contains it?

Thanks

Can you provide a link as to where you've seen this?

If it's from links such as:
http://stackoverflow.com/questions/11376767/vector-subscription-error-in-c
or
the first few link brought up by the "google search engine"

then those were functions created by the individual programmers.

This is code illustrated in the above link:

//asks a number within a range ans keeps asking untill the number is within that range, next it return that number within the specific range
int askNumber(string question, int high, int low)
{
int number;
do
{
    cout <<question << " (" <<low <<" - " <<high <<"): ";
    cin  >> number;
}while (number > high || number < low);

return number;
}

Most likely you were taught how to write the function yourself early in your course or textbook and simply forgot that it was something you had to make yourself.
