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


/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char** argv) {
    
    string s;
    char p[10];
    char q[10];

    //cin.getline(p,4);//最大只能接受3个字符，自动在末尾加上'\0' 
    cout<<"p="<<p<<endl;
    
    cin.getline(q,3,'\0');//输入字符串以'\0' 结尾 ,大只能接受3个字符
    cout<<"q="<<q<<endl;
    

    
    getline(cin,s);
    cout<<"s"<<s<<endl;

    cout<<"p="<<p<<endl; 
    cout<<"q="<<q<<endl; 
    cout<<"s"<<s<<endl;
    return 0;
