[游戏开发]char*cstr 转 ushort

废话不多说，直接上代码

#include <iostream>
#include <Windows.h>
using namespace std;

int hexCharToInt(char c)
{
	if (c >= '0' && c <= '9') return (c - '0');
	if (c >= 'A' && c <= 'F') return (c - 'A' + 10);
	if (c >= 'a' && c <= 'f') return (c - 'a' + 10);
	return 0;
}

void cstr_to_ushort(char* cstr, USHORT& str_ushort)
{
	for (int i = 0; i < 4; i++) {
		char tmp;		
		strncpy(&tmp, &cstr[i], 1);
		cout << "tmp = " << tmp << endl;
		int ai = hexCharToInt(tmp);
		str_ushort = str_ushort | ai << (12 - 4 * i);
		cout << str_ushort << endl;
	}
}

int main()
{
	char a[5] = "04F3";
	USHORT us = 0;
	cstr_to_ushort(a, us);
	printf("%x", us);

	int res = getchar();
	return 0;
}
