本文介绍了一种在C/C++中实现字符(char)与宽字符(wchar_t)相互转换的方法。通过两个函数charTowchar和wcharTochar，演示了如何使用Windows API中的MultiByteToWideChar和WideCharToMultiByte函数进行编码转换。示例代码展示了从char到wchar_t及反向转换的过程。

#include <windows.h>
#include <stdio.h>

//function: charTowchar
//purpose:char to WCHAR 、wchar_t、LPWSTR etc
void charTowchar(const char *chr, wchar_t *wchar, int size)
{   
	MultiByteToWideChar( CP_ACP, 0, chr,
        strlen(chr)+1, wchar, size/sizeof(wchar[0]) );
}

//function: wcharTochar
//purpose:WCHAR 、wchar_t、LPWSTR to char
void wcharTochar(const wchar_t *wchar, char *chr, int length)
{
    WideCharToMultiByte( CP_ACP, 0, wchar, -1,
        chr, length, NULL, NULL );
}

int main (void)
{
	char     chr[128];
	wchar_t  *wchar = L"陈鸿钦";


	//wchar_t to char
	wcharTochar(wchar, chr, sizeof(chr));
	printf("char is %s\n", chr);

	//char to wchar_t
	wchar = (wchar_t *)malloc(sizeof(wchar_t) * 64);
	charTowchar(chr, wchar, sizeof(wchar_t) * 64);

	wprintf_s(L"%s\n", wchar);//
	getchar();

	return 0;
}
