浅谈c++ 字符类型总结区别wchar_t,char,WCHAR

1、区别wchar_t,char,WCHAR ANSI：即 char，可用字符串处理函数：strcat( ),strcpy( ), strlen( )等以str打头的函数。 UNICODE：wchar_t是Unicode字符的数据类型，它实际定义在里： typedef unsigned short wchar_t; 另外，在头文件中有这样的定义：typedef wchar_t WCHAR; 所以WCHAR实际就是wchar_t wchar_t 可用字符串处理函数：wcscat(),wcscpy(),wcslen()等以wcs打头的函数。为了让编译器识别Unicode字符串，必须以在前面加一个“
