Okay so let's say i have a string passed on to me:
a = "hello;theyarearbitrary;lengths; "
i want just the words before ';'. i know i can use getline, but it would only get the first word and won't go through the rest, how would i get the rest of the words: theyarearbitrary;lengths; "?

I'm not sure what lang you are using, but there should be something called a "delimeter" in your case ';' is the delimeter.

I'm using c++.  I know i can use getline(string, 100, ';')
but wouldn't that just get "hello"
What if i wanted to also get "theyarearbitrary"
and "lengths"?

sanchez9457 · Answer

Doesn't getline just get the first thing before the delimeter then ignore the rest?

konradzuse · Answer

oic there are 3 words,. sorry....  you can go through the delimeter multiple times.

sanchez9457 · Answer

How would you do that though? do you have to create a loop for getline?

konradzuse · Answer

not too sure how it works in C++, it should all be on the same line....

Actually, you'd probably be better off using a scanner type class to tokenize the input string and then concatenate it back as you want.

konradzuse · Answer

oh yeah I forgot about tokenizers :).  I saw the word once and checked it out briefly....  I don't do much with strings and stuff....  My dad loves them, but I don't use them much....

Would it possible if one of you were to examplin it to me? i searched for it but i am lost.

http://www.cplusplus.com/reference/cstring/strtok/ I thought the STL had a token class, guess not.
