用C++实现字符的逆转

#include <iostream>
#include <Windows.h>
#include <string.h>

using namespace std;

void reverse(unsigned char *a)
{
	unsigned char *p1=a;
	unsigned char tmp[1024];
	unsigned char *p2;
	unsigned int len=strlen((char *)a);
	p2=len+tmp;//传的是地址，等式左边不能是指针

	*p2--='\0';
	while(*p1)
	{
		if(*p1<0x80)
		{
			*p2--=*p1++;
		}else
		{
			*(p2-1)=*p1++;
			*p2=*p1++;
			p2=p2-2;
		}
		
	}

	for(int i=0;i<len;i++)
	{
		a[i]=tmp[i];
	}


	

}

int main(void)
{
	unsigned char str[1024];
	
	cout<<"请输入你要转换的字符：";
	cin>>str;

	reverse(str);

	
	cout<<"转换的结果为："<<str<<endl;

	system("pause");
	return 0;
}

运行结果：
