Odd issue with white space.

[Jabberwiccy]

Hey, I've got a C++ program that's been stumping me all week. The assignment called for a program that converts a phrase/string into corresponding telephone digits (2 for a, b, and c, etc.). That part wasn't a problem. What's been confusing me is that when there's a space in the input, the program stop reading the string (i.e, if the input is 'the root', it will process the 'the', and then run the exit loop. Here's the code so that hopefully one of you guys can give me a hand.

Thanks, J.

It's because you are using cin >> sWord. cin skips all whitespace, and also stops input based on whitespace. So if you enter "the root", cin will take "the" first, then "root". You should use getline(cin, sWord) in order to get all the input from the beginning to the enter key.

That worked! Thanks a lot!
