The Best Way to Manipulate Strings in C++

The Best Way to Manipulate Strings in C++

You should use the String class to avoid common problems when manipulating strings in C++. The following approach will work, but it needs a lot more code to make it robust:


What if the instring was sent in as null, or what if it was 80 chars in length? To avoid these common problems it is best to use some kind of String class to do all of your string processing. Almost all compiler vendors include a String class with their implementations. String classes provide methods and operators to construct, assign, copy, read, and write to streams and many more operations.

If I had used the STL string class instead of char arrays and pointers, the previous example would look like this:

 #include #include void foo(const string & instring){	string read_string; // construct a string object	cin >> read_string;	if (instring == read_string)		// .. do something else		//... do something else.}
