These two days have been addressing such a problem, the project has the following requirements: Embedded products, the algorithm part of the implementation of C + +, while the control program and other programs with C implementation. This requires that the C + + algorithm can be invoked through the program. At the same time, the project has a PC demo program,

It defines the TCHAR type, which is a single-byte character on the Win9x platform and a double-byte Unicode character on the WinNT platform. For each function that accepts a string or struct (which contains character data), the Win32 API defines two versions of the structure, the Ansi encoding with A suffix, and the
