c++ 中文与GBK编码值相互转换

#include<iostream>
#include<string>
#include<vector>
using namespace std;

//获取中文字段的GBK编码值
vector<unsigned char> encode(const string s)
{
string str = s;
vector<unsigned char> buff;

int len = str.length();
buff.resize(len);
memcpy(&buff[0], str.c_str(), len);

return buff;
}

//把GBK编码值解码成中文字段
string decode(vector<unsigned char> buff)
{
vector<unsigned char>debuf = buff;
debuf.resize(buff.size() + 1);
string str = (char *)&debuf[0];
return str;
}

int main() {
//编码
vector<unsigned char>str;
string s = "牧濑红莉栖是我老婆";
str = encode(s);
printf("gbk编码值：");
for (int i = 0; i < str.size(); i++) {
printf("%X ", str[i]);
}
printf("\n");

//解码
string k2 = decode(str);
printf("中文值：");
printf("%s\n", k2.c_str());

system("pause");
return 0;
}
