How do I tokenize a string in C++?

Hello I was wondering how I would tokenize a std string with strtok

string line = "hello, world, bye";    
char * pch = strtok(line.c_str(),",");

I get the following error

error: invalid conversion from ‘const char*’ to ‘char*’
error: initializing argument 1 of ‘char* strtok(char*, const char*)’

I’m looking for a quick and easy approach to this as I don’t think it requires much time

Answer 1

I always use getline for such tasks.

istringstream is(line);
string part;
while (getline(is, part, ','))
  cout << part << endl;
