Give a matrix m with N lines and N columns and two numbers i and j representing the position in the array of the first element of a parallel to the main diagonal. Show all the elements from the top down from that parallel to the diagonal.
        Input data
             From the first line, read the N number on the keypad. The following N lines read N natural numbers representing the coordinates of the matrix. The last line reads the numbers i and j.
       Output data
           The program will display on screen a number of numbers representing the elements on the diagonal parallel.

Restrictions and clarifications

  • 1 <= N <= 50
  • 0 < i ,j <= N
  • 1 <= m[i][j] <= 100

    always i = 1 or j = 1
The lines and columns are numbered 1 to N

#include<iostream>

using namespace std;

int

main ()

{

  int m[51][51], i, j, n, d;

  cout << "n=";

  cin >> n;

  cout << "intoducere elemente matrice= " << endl;

  for (i = 1; i <= n; i++)

    for (j = 1; j <= n; j++)

      {

//cout << "m[" << i << "," << j << "]=";

cin >> m[i][j];

      }

  cout << "i,j=";

  cin >> i >> j;

  if (i < j)

    {

      d = j - 1;

    }

  else

    {

      d = i - 1;

    }

  if (i < j)

    {

      cout << "parcugere matrice deasupra diagonalei principala= " << endl;

      for (i = 1; i < n; i++)

{

  j = i + d;

  if (j <= n)

    {

      cout << m[i][j] << "  ";

    }

}

      cout << endl;

    }

  else

    {

      cout << "parcugere matrice sub diagonala principala= " << endl;

      for (i = 2; i <= n; i++)

{

  j = i - d;

  if (j > 0)

    {

      cout << m[i][j] << "   ";

    }

}

      cout << endl;

    }

  return 0;

}

Anyone please you confirm this algorithm is correct for this problem?

If you have any solution please help me.Thanks.
