Why doesn't that work?

std::string Contostr(int num){ std::stringstream ss; ss << num; ss.str(); return num; } And is there any other ways to do so?

KarSah, i have already managed the problem: std::string Contostr(int num){ std::string str; std::stringstream ss; ss << num; ss >> str; return str; }

I am not sure,but i think its becouse your function must return std::string but you are returning int

KarSah, but doesn't num converts to string in this line: ss.str(), as i added num here: ss<<num;?

Oleg Storm,i think no, cause num is another variable,if i understand correctly you need to return ss

Oleg Storm,no problem😊,but you can make it without another string variable,simply returning ss.str() std::string Contostr(int num){ std::stringstream ss; ss << num; return ss.str(); }
