Convert a string with various float numbers into floats.

I have a series of strings like this "50 50 10"

Each number is supposed to represent the x, y, and z values of an origin. I want to convert each number of this string into an actual float.

I tried using atof, but that gave me back just the first number, 50 in this case.

Any ideas?

Thank you!

The best way to do this would be to use the string stream. This site: has a great tutorial for it. It will also allow for direct casting from string to whatever type you need. (In this case float.)

Use a istringstream,

int main() {

    string s = "50 50 50";

    istringstream instream;
    instream.str(s);

    double a, b, c;
    instream >> a >> b >> c;
    return 0;
}
