Dev-C++ using variables in functions?

[Craig321]

Hi,

I have this code to backup my save-game(s):

std::ifstream ifs("Craig06.usr", std::ios::binary);
std::ofstream ofs("Craig06Backup.usr", std::ios::binary);

ofs << ifs.rdbuf();

Rather than using the name Craig06Backup.usr I'd like to be able to do Craig06<current_date>.usr to avoid it overwriting the previous backup.

So, any idea how I can use variables in that bit of coding please?

Thanks,
Craig.

Don't think it does work, it compiles but then the copy doesn't work anymore
