Answer 1

#include <iostream>
using namespace std;
int main(void)
{
char a;
cout<<"请输入一个字符，若要退出程序，请输入!:"<<endl;
cin>>a;
while(a != '!')
{
cout<<a<<endl;
cin>>a;
}
cout<<"退出程序!"<<endl;
return 0;
}

Answer 2

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

class CString
{
private:
vector<string> q;
public:
void add();
void print();
};
void CString::add()
{
string w;
cout<<"Please input string"<<endl;
cin>>w;
q.push_back(w);
}
void CString::print()
{
cout<<endl<<"The string is:"<<endl;
for(int i = 0;i < q.size();i++)
cout<<q[i].c_str()<<endl;
cout<<endl;
}

int main()
{
CString s;
while(1)
{
s.add();
s.print();
}
return 0;
}
