#include <iostream> using namespace std; int a[110][110]; int main(){ int n,m; cin>>n>>m; for(int i=1;i<=n;i++){ for(int j=1;j<=m;j++){ cin>>a[i][j]; } } for(int i=1;i<=n;i++){ for(int j=1;j<=m;j++){ cout<<a[i][j]<<" "; } cout<<endl; } return 0; }

特简单，一维数组简单解决 求赞

#include <iostream> using namespace std; int main (){ int a,b; cin >> a >> b; for (int i = 1; i <= a; i++){ for (int j = 1; j <= b; j++){ int f; cin >> f; cout << f << ' '; } cout << endl; } return 0; } 其实可以不用二维数组

#include <bits/stdc++.h> using namespace std; int a[110][110]; int main(){ int n,m; cin>>n>>m; for(int i=1;i<=n;i++){ for(int j=1;j<=m;j++){ cin>>a[i][j]; } } for(int i=1;i<=n;i++){ for(int j=1;j<=m;j++){ cout<<a[i][j]<<" "; } cout<<endl; } return 0; }

#include<iostream> using namespace std; int main() { int a, b, num;; cin >> a >> b; int nums = a * b; while (nums--) { cin >> num; cout << num << " "; if (nums % b == 0) { cout << endl; } } }

比较复杂 本题考查二维数组，循环嵌套。 二维数组和循环记得考虑范围，不记住的话csp,Noip容易失分 下面是代码： #include<bits/stdc++.h> using namespace std; int main(){ int n,m; cin>>n>>m; int a[105][105]; for(int i = 0;i<n;i++){ for(int j = 0;j<m;j++){ cin>>a[i][j]; } } for(int i = 0;i<n;i++){ for(int j = 0;j<m;j++){ cout<<a[i][j]<<" "; } cout<<endl; } }

#include<bits/stdc++.h> using namespace std; int a[101][101]; int main(){ int n,m; cin>>n>>m; for(int i=0;i<n;i++){ for(int j=0;j<m;j++){ cin>>a[i][j]; } } for(int i=0;i<n;i++){ for(int j=0;j<m;j++){ cout<<a[i][j]<<" "; } cout<<endl; } return 0; }

#include<bits/stdc++.h> using namespace std; int n,m; int a[110][110]; int main(){ cin>>n>>m; for(int i=0;i<n;i++){ for(int j=0;j<m;j++){ cin>>a[i][j]; } } for(int i=0;i<n;i++){ for(int j=0;j<m;j++){ cout<<a[i][j]<<' '; } cout<<endl; } return 0; }

#include<iostream> using namespace std; int main(){ （如果想看里面，请点进去哦） } 求点赞！
