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;

implementing split function in c++

// splits a std::string into vector<string> at a delimiter
vector<string> split(string x, char delim = ' ')
{
    x += delim; //includes a delimiter at the end so last word is also read
    vector<string> splitted;
    string temp = "";
    for (int i = 0; i < x.length(); i++)
    {
        if (x[i] == delim)
        {
            splitted.push_back(temp); //store words in "splitted" vector
            temp = "";
            i++;
        }
        temp += x[i];
    }
    return splitted;
}
