I'm new to C++ and would like some help on how I can extract more than one parameter from a string. I have an example of a function that will receive the string. The string contains two parameters and I don't know how to pull off the second parameter. Thanks in Advance.

Code:void Message_Received(std::istream& args) { unsigned msg; // Pull off the first param in the string args >> msg; // Pull off the second param in the string ???? }
If it's another unsigned value, for instance, you simply repeat the extraction from the stream like you did for the first parameter:
Or you could just put everything on one line:Code:void Message_Received(std::istream& args) { unsigned msg, msg2; // Pull off the first param in the stream args >> msg; // Pull off the second param in the stream args >> msg2; ... }
[edit]Be careful you don't confuse yourself over strings vs streams, they are different things and what you are talking about here are the latter.[/edit]Code:void Message_Received(std::istream& args) { unsigned msg, msg2; // Pull off the params from the stream args >> msg >> msg2; ... }

Thanks so much for your help and clarification on strings vs streams. I was able to implement what you said and it works!
