C++: how to add int to current string in C++?

Question

C++ concatenate string and int

Hi,

In C# I can write like this:

int i = 0;
string text = "out.jpg";
while(true)
{
     i++;
     Object.write(i+text, stream);
}

But this is not true for C++. the problem is at: i + default.

How could I fix this in C++?

Thanks in advance. Your help is much appreciated!

Answer 1

default is a keyword in C++. You can't have string default in C++. And I don't see what you are trying to achieve. Please clarify

Answer 2

take a look at stringstreams or boost.format http://www.boost.org/doc/libs/1_38_0/libs/format/doc/format.html

boost::format("%1%%2%") % i % default_;

Answer 3

You could use a stringstream...

std::stringstream ss;
ss << i << text;
Object.write(ss.str(), stream);

Answer 4

default is a reserved keyword. Change the variable name to defaultStr or similar, and everything should work fine.
