Random order
Author
Hi!
I have an std::string "1A 2B 3C 4D". And now i want to make out of it a random ordered std::string, e.g., "3C 1A 4D 2B".
But i dont know how to make it. Can somebody help me?
Thanks, Christian
Split it up into four strings and randomly merge them together into a new one.

Yeah... i only have the problem with spiltting the 4 parts. Oh and this function should work with n parts.
I''ve never coded with the std::string but:

edit: in the joy of creation, I didn't think this could be a homework question. Solution removed.
Hint: use stringstream to split the string into smaller strings (it splits on whitespace)

It is no homework. I dont have computer/software development in school. It is for a projekt i am working at.
Well, I hope this helps then:
(untested)
int main() { using namespace std; string input = "1A 2B 3C 4D"; stringstream ss(input); vector<string> tokens; while (ss.good()) { string text; ss >> text; tokens.push_back(text); } random_shuffle(tokens.begin(), tokens.end()); stringstream result_ss; copy(tokens.begin(), tokens.end(), ostream_iterator<string>(result_ss, " ")); string output = result_ss.str();} This topic is closed to new replies.
