Answer 1

#include<iostream>

using namespace std;
int main()
{
    int n;
    cout << "n = ",cin >> n;
    int A[n+1][n+1];
    cout <<"1: \n";
    for(int i = 1; i <=n; i++)
    {
         if(i % 2 == 0)
              for(int j = n; j>0; j--)
              {
                    A[i][j] = j;
                    cout << A[i][j]<<" ";
              }
         else
              for(int j = 1; j<=n; j++)
              {
                    A[i][j] = j;
                    cout << A[i][j]<<" ";
              }
         cout <<"\n";
    }
    
    cout <<"\n7: \n";
    for( int i = 1; i<=n/2; i++, cout <<"\n")
         for( int j = 1; j<=n; j++)
              cout <<(A[i][j] = (j>=i&&j<=n-i+1))<<" ";
    
    for( int i = n/2+1; i<=n; i++, cout <<"\n")
         for( int j = 1; j<=n; j++)
              cout <<(A[i][j] = (j>=n-i+1&&j<=i))<<" ";
    
    system("Pause");
    return 0;
}

Answer 2

#include <iostream>
using namespace std;

int main() {
int n=7;
int a[n][n];
for (int i=0; i<n/2; i++){
  for (int j=0; j<i; j++) a[i][j] = 0;
  for (int j=i; j<n-i; j++) a[i][j] = 1;
  for (int j=n-i; j<n; j++) a[i][j] = 0;
}
for (int i=n/2; i<n; i++){
  for (int j=0; j<n-i-1; j++) a[i][j] = 0;
  for (int j=n-i-1; j<i+1; j++) a[i][j] = 1;
  for (int j=i+1; j<n; j++) a[i][j] = 0;
}
for (int i=0; i<n; i++){
  for (int j=0; j<n; j++) cout << a[i][j];
  cout << "\n";
}
return 0;
}
