十六进制转换ASCII码的问题.在VC编译下.为什么就有问题.大家帮我看看.谢谢.
// 2.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
void hctoa(unsigned char ch, unsigned char* hex)
{
unsigned char i,c;

for(i=0;i<2;i++)
{
if(i==0) c = ch>>4;
else c = ch;
c &= 0x0f;
if( c>=0 && c<=9 ) *(hex+i) = '0' + c;
else *(hex+i) = 'A' + c - 10;
}
}

int main(int argc, char* argv[])
{
unsigned char crsp[2];
unsigned char str=22;
unsigned char i;

hctoa(str,crsp);

for(i=0;i<2;i++)
{
printf("%c",crsp[i]);
}

printf("Hello World!\n");
return 0;
}
