How to joint 2 int???

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,
ken js

Like multiplying a by 100 perhaps?

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;

---

Or the answers on other forums - enjoy the variety in the answers.

That's going to result in "207" not "2007."

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.
