Why doesn't that work?

Question

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

Anyway, thanks for your help🤗

Answer 6

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();
}
