Converting Bases in c++

[ChimpFace9000]

To turn a number in ascii in any base in c i would use sprintf. Whats the c++ equivelent?

Is this the sort of thing you mean:

cout << hex << 100 << oct << 255 << endl;

?

Or did you want something for any random base? Doesn't itoa have a radix argument?

[SteveCRM]

yeah it does

itoa(number, string it goes in, base you want);

Thnks parksie but i need to do it into a buffer. Its for a windows app.

Isnt itoa a c function?

[SteveCRM]

works for me in windows programs...thats the only way I've been taught to output numbers in windows

what are the things for the different bases? i tried bin but it didn't work (for binary)

To get it into a buffer use stringstream (header <sstream>, for <string> objects) or strstream (header <strstream>, for char* C-style strings).

stringstream ss;
ss << hex << 100 << oct << 255 << endl;

There seems to be no way to choose any base, setbase only accepts 8, 10 and 16 as arguments.
