Once you assign a string to aStringvariable, that string isimmutable, which means you cannot change its length or contents. When you alter a string in any way, Visual Basic creates a new string and abandons the previous one. TheStringvariable then points to the new string. ...

This means that the following common assumptions that C and C++ programmers or that libraries written in C or C++ might make about strings are not necessarily valid when applied to String objects: The value returned by the strlen or wcslen functions does not necessarily equal String.Length. The...
Reentrant means the functions are thread safe, and can be safely used in a multithreaded environment. The function we have been discussing has a reentrant version called strtok_r(), but with a different signature. Take a look at the man pages (man strtok). Reentrant library functions are a...
It means that a string of length n has an nth element indexed by the number n - 1. operator[] is faster than the member function at for providing read and write access to the elements of a string. operator[] doesn't check whether the index passed as a parameter is valid, but the ...
