//主要训练自己在vector和重载函数的编程能力，所以写得比较复杂
#include<iostream>
#include<vector>

const std::vector<char>& MyStrcat(std::vector<char>& dstStr,const std::vector<char>& srcStr)
{
    for(char c : srcStr)
        dstStr.push_back(c);
    return dstStr;
}

std::istream& operator>>(std::istream& stream, std::vector<char>& s)
{
    char c;
    while (stream.get(c) && c != ' ' && c != '\n') // 以空格或换行符作为两个字符串的分隔符
        s.push_back(c);
    return stream;
}
