AnsiString myString = "Hello world!"; int len = myString.Length(); // len = 12
AnsiString myString = ""; bool isEmpty = (myString.Length() == 0); // isEmpty = trueThis example demonstrates how to use AnsiString Length to check if a string is empty. We first initialize an AnsiString object `myString` to an empty string. We then call the Length function on `myString` and compare the result to 0. If the length is 0, then the string is empty. In this case, `isEmpty` will be true. Package library: VCL (Visual Component Library) is a package library in C++Builder that provides a set of functions for creating visual applications. The AnsiString class is part of this library.
