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...
A Null-Terminated String is defined as a character string in which the length computation starts at the beginning and examines each character sequentially until it reaches a null character. This method, commonly used in C programs, requires time proportional to the length of the string for computa...
