Re: Working with strings in c++

Hi. I'm a C++ newbie. I need to split the following variable into

const CString& myStr = "val1;val2;val3";
First thing you should look at is the documentation of MFC's CString class.
There, you will find functions to search (I guess you want to split the
string at the ';' ) and to retrieve a range of characters (substring).
Then, you need to decide how you want to use this. Will you always have
three strings? Will there be empty strings? Do you need them in an array
(CStringArray) or can you live with extracting them step by step? Depending
on that, you code a function that does the necessary steps.
Then, you write code that only tests that function (unittests). For example,
you call it with the above string and afterwards use ASSERT() to check that
the extracted string is "val1" while the remainder is "val2;val3", assuming
you extract them step by step.
