Hi,
e.g.
int a = 20;
int b = 07;
I want to joint a and b together to get 2007.
Anybody know how to do it?
lots of help,

Like multiplying a by 100 perhaps?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Not very generic. I think what you want is to convert both to strings and concatenate them. As in:
Code:std::ostringstream str; str << a << b; std::cout << str.str() << std::endl;
All the buzzt!

That's going to result in "207" not "2007."Originally Posted by CornedBee
The line:
int b = 07;
Is bogus anyway, because the literal is being treated as octal. For this value it doesn't matter, but...
It always amazes me how easy it is to overlook these things.

Or, the convoluted way:
Output 20,0,7 to a txt. file(app), close, reopen the file then retrieve as a string.
