练习 5.21 修改5.5.1节（第171页）练习题的程序，使其找到的重复单词必须以大写字母开头。
环境：Linux Ubuntu（云服务器）
工具：vim
代码块
#include<iostream>
#include<string>
#include<vector>
using namespace std;int main(){vector<string> str;string s;while(cin>>s){str.push_back(s);}int upper = 0;int sign = 0;string temp;for(auto beg : str){if(beg[0] >= 'A' && beg[0] <= 'Z' && upper == 0){temp = beg;upper = 1;continue;}else if(beg[0] >= 'a' && beg[0] <= 'z'){upper = 0;continue;}if(beg == temp && upper == 1){sign = 1;break;}}if(sign == 1){cout<<"The word is "<<temp<<endl;}else{cout<<"No word is repeated continuously."<<endl;}return 0;
}
运行结果显示如下
