c++ - Looking for the most elegant solution for looping a specific string -

so got dozen of strings download , 1 of example one

"australija 036 aud 1 5,136250 5,151705 5,167160"

the spaces shown single here, multiple between numbers , chars.

so first idea count manually number need (the second one, 5.151705 in example) , substring.(41,8) seems ify me.

second idea save number chars in vector, , vector[4] , save seperate variable.

and third 1 loop string until position myself after 5th group of spaces , substring it.

just looking feedback on "best".

you can think of first trimming multiple whitespace. like

std::string str = "australija  036   aud  1  5,136250  5,151705   5,167160"; str.erase(std::unique(str.begin(), str.end(), [](char a, char b) {         return ::isspace(a) && ::isspace(b);     }), str.end()); 

a string split may useful

std::vector<std::string> split(std::string & str, char delim) {     std::vector<std::string> result;     std::stringstream ss(str);     std::string token;     while (getline(ss, token, delim)) result.push_back(token);     return result; } 

and calling it

std::vector<std::string> result = split(str, ' ');
