Thankx, but I knew that Numbers are converted to strings when you write
them on stdout with cout << ...
What I want to do is writing that what in your examples appears on the
screen to a variable of the type "string".
Tilo Riemer just wrote me, that I can use "sprintf". But then I have to
guess how many digits number will have. So it would be great if there
was something like "sprintf" for instances of the string class. Any
idea?
