    split space sepparated string

    Hi everyone,

    How do I split a string like this
    "500 57 - 33 + 17 * 22 -"

    into an array of strings
    "500" "57" "-" "33" ..

    What function can do that for me?

    Yes. strtok() for example. sscanf() could also be used with some thinking about it.

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    It should also be quite simple with stringstream and operator >>.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
    Quoted more than 1000 times (I hope).

    yeah use a stringstream

    Code:
    std::stringstream ss(the_string);
    std::vector<std::string> strings;
    std::string tmp;
    
    while(ss>>tmp)
        strings.push_back(tmp);
