vector<int> nlist;
while(cin>>s)
{
for (int i = 0; i < vlist.size(); ++i)
{
if (vlist.at(i) == s) ++nlist.at(i);
}
if (i == vlist.size())
{
vlist.push_back(s)
nlist.push_back(0);
}
}
for (int i = 0; i < nlist.size(); ++i)
{
if (nlist.at(i))
{
cout<<"重复字符串"<<vlist.at(i)<<endl;
cout<<"重复次数"<<nlist.at(i)<<endl;
}
return 0;
}

定义个struct，其内有char变量和对应的int，循环遍历，返回那个struct的list
