Question

I have a string, which looks like this:

foo
$RESULT :(0.2374742, 0.267722, ...up to a million more)
$STATES :{1, 3, 5, ...}
foo 

so somewhere in the string are results and directly after them are the states and I want to save the Results in a list and the states in another list.

I think I need something like “read from $RESULT :(” to “)” get every number and push to list, same for States, but I dont know how to read a String from “a” to “b” and tokenize its content.

Answer 1

int index = s.find("RESULT: (");
int index2 = s.find("$STATE");

int length = index2 - index;

if (index != string::npos) {
    temp = s.substr(index + 7, length - 8);
}
typedef tokenizer<char_separator<char> > tokenizer;
char_separator<char> sep(",() ");
tokenizer tokens(temp, sep);
for (tokenizer::iterator tok_iter = tokens.begin();
        tok_iter != tokens.end(); ++tok_iter) {
    basic_string<char> tempValue = *tok_iter;

    values.push_back(tempValue);

}
