请教关于字符串的输入问题
程序代码：#include<iostream>
#include<string>
using namespace std;
class stu
{
public:
void set();
void put();
private:
int num;
string name;
string phone;
};
void stu::set()
{
cout << "num is:";
cin >> num;
cout << "name is:";
cin>>name;
cout << "phone is:";
cin >> phone;
cout<<endl;
}
void stu::put()
{
cout << "num\t" << "name\t" << "phone" << endl;
cout << num << "\t" << name << "\t" << phone << endl;
}
int main()
{
class stu student1;
student1.set();
student1.put();
return 0;
}输入 1 li ming 124345时，来不及输入12345就直接得到结果了，书上好像看到过，但找不到了，请问该如何修改
