#include <bits/stdc++.h> using namespace std; int main() { int n; cin>>n; for(int i = 0;i < n;i++){ for(int j = 1;j <= n;j++){ cout<<j+i*n<<' '; } cout<<endl; } return 0; }

能给个赞吗ovo

#include<iostream> using namespace std; int n,sum=1; int main(){ int n; cin>>n; for(int i=0;i<n;i++){ for(int j=0;j<n;j++){ cout<<sum<<' '; sum++; } cout<<endl; } }

#include<iostream> using namespace std; int a[15][15]; int n; int main(){ cin >> n; int sum = 1; for(int i = 1;i <= n;i++){ for(int j = 1;j <= n;j++){ a[i][j] = sum; cout << a[i][j] << " "; sum++; } cout << "\n"; } return 0; }
