#include<iostream> #include<string> using namespace std; int main(){ string a,b,c; getline(cin,a); getline(cin,b); getline(cin,c); cout<<a<<endl<<b<<endl<<c; }

#include <iostream> using namespace std; int main(){ int a,b,c,d,e,f,g, h,i; cin>>a>>b>>c>>d>> e>>f>>g>>h>>i; cout<<a<<" "<<b<<" "<<c <<endl<<d<<" "<<e<< " "<<f<<endl<<g<<" " <<h<<" "<<i; return 0; }

（1）二维数组做法 （2）定义9个变量

#include<bits/stdc++.h> using namespace std; int a,b,c,d,e,f,g,h,i; int main(){ cin>>a>>b>>c>>d>>e>>f>>g>>h>>i; cout<<a<<" "<<b<<" "<<c<<"\n"; cout<<d<<" "<<e<<" "<<f<<"\n"; cout<<g<<" "<<h<<" "<<i; return 0; }
