VC Data types

string processing and mutual conversions under different coding formats:

The data types that people often encounter when programming:
Ansi:
Char, char *, const char *
CHAR, (PCHAR, PSTR, LPSTR), LPCSTR

Unicode:
wchar_t, wchar_t *, const wchar_t *
WCHAR, (Pwchar, Pwstr, LPWSTR), LPCWSTR

T generic type:
TCHAR, (TCHAR *, Ptchar, PTSTR, LPTSTR), LPCTSTR

Above, where: P represents the meaning of the pointer, str stands for the meaning of the string, L is the meaning of the long pointer, can be ignored under the WIN32 platform, C stands for the meaning of the const constant, W stands for the meaning of the wide wide byte, t everyone can understand the meaning of the universal type,
It is possible to define _UNICODE macros according to the project, respectively, to define different types, such as: TCHAR type, if _UNICODE macro is defined in the project, then he is ultimately defined as the wchar_t type,
If the _UNICODE macro is not defined in the project, then TCHAR is ultimately defined as a char type.

Its convenience is to modify the coding format of the project without modifying the code, so it is recommended that you use the common type when writing programs!
