c++ string split to array code example

Example 1: split a string based on a delimiter in c++

void tokenize(string &str, char delim, vector<string> &out)
{
	size_t start;
	size_t end = 0;

	while ((start = str.find_first_not_of(delim, end)) != string::npos)
	{
		end = str.find(delim, start);
		out.push_back(str.substr(start, end - start));
	}
}

int main()
{
    string s="a;b;c";
    char d=';';
    vector<string> a;
    tokenize(s,d,a);
    for(auto it:a)  cout<<it<<" ";

    return 0;
}

Example 2: c++ string split

std::vector<std::string> &split(const std::string &s, char delim, std::vector<std::string> &elems) {
    std::stringstream ss(s);
    std::string item;
    while(std::getline(ss, item, delim)) {
        elems.push_back(item);
    }
    return elems;
}
