How I do Split?

How I do split in C++ ?

Ex:

test1;;test2;;test3

How do I take those and stick those in variables ?

In perl would be

my($var1,$var2,$var3)=split(/;;/, $input);

How do I do that in c++ ?

I never thought of it myself though I use it PHP, so I decided to write an implementation:

Code:

---

bool split(std::string sep, std::string str, std::vector<std::string> &array) {
        int seplen = sep.length();
        if (seplen < 1)
                return false;
        int len = str.length();
        int find = 0, prev = 0;
        for (;;) {
                if (find = str.find(sep, find) == std::string::npos) {
                        array.push_back(str.substr(prev, len - prev));
                        return true;
                }
                else {
                        array.push_back(str.substr(prev, find - prev));
                        find += seplen;
                        prev = find;
                }
        }
        return false;
}

probably could be optimised though.
The difference would be that we would be passing a vector of strings by reference, and then accessing the elements of the vector, rather than directly assigning the values to individual variables.
