#include<bits/stdc++.h> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a<<endl; cout<<b<<endl; }

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

简单

#include <iostream> using namespace std;int main(){int a,b;cin>>a>>b;printf("%d\n%d\n",a,b);return 0;}

话不多说直接上代码 #include <bits/stdc++.h> using namespace std; void print(int a,int b){ cout<<a<<"\n"<<b; } int main(){ int a,b; cin>>a>>b; print(a,b); return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a<<endl; cout<<b; return 0; }

#include<iostream> using namespace std; int main(){ int a,b; cin>>a>>b; cout <<a <<endl<<b; return 0; }

#include <bits/stdc++.h> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a<<endl; cout<<b; return 0; }

a=int(input()) b=int(input()) print(a) print(b)

#include<bits/stdc++.h> using namespace std; int main(){ int x,y; cin>>x>>y; cout<<x<<endl<<y; return 0; }

#include <iostream> using namespace std; int main(){ int a,b; cin >> a >> b; cout << a <<endl; cout << b ; return 0; }

#include<bits/stdc++.h> using namespace std; int main() { int x,y; scanf("%d%d",&x,&y); printf("%d\n%d",x,y); return 0; }

如果这都不会，建议看题解中的注释

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

#include <bits/stdc++.h> using namespace std; int main() { int n,m; cin >> n >> m; cout << n << endl << m; return 0; }

#include<iostream> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a <<endl; cout<<b; return 0; }
