Append an integer to an stl string

[César]

Hi,

I need to append an integer to a stl string. I´ve tried many solutions
and the only one that works is using the c functions 'itoa' or 'sprintf'.
Is there any "smarter" way to do this?

Thanks in advance.

std:stringstream lStream; lStream << SomeInt;

MyString += lStream.str();

Or use boost::lexical_cast which basically packages up this into a single
function:

MyString += boos::lexical_cast<std::string>(SomeInt);

std:stringstream lStream; lStream << SomeInt;

Oops, should be stdstringstream;

MyString += lStream.str();

Or use boost::lexical_cast which basically packages up this into a single
function:

MyString += boos::lexical_cast<std::string>(SomeInt);

Which I've just demonstrated is easier to remember than the above.

Thanks to all . At the end I´m going to use the "lexical_cast".
I´m also glad for the links you have written, they will ll be very useful
for me.
