Question

Write a C++ function that takes a two dimensional dynamic array (matrix) and its sizes and returns true if the matrix is an upper matrix and returns false otherwise. Remark: A matrix M is an upper matrix if it is a square matrix (row size = column size) and every element M[i][j] = 0 for all i > j. That is all the elements of the matrix below the main diagonal are zero.

Answer 1

Code

//Function name isUpperMatrix that recive 2d array as pointer and the sizes that is number of rows ans num

//columns

bool isUpperMatrix(int **mat, int row, int col)
{
   if (row != col)//fist will check if row and col are same size fo square matrix
       return false;//if not then return false
   for(int i=0;i<row;i++)//then will check for next condition if the element at first diagonal is 0 if not then return false
       for (int j = 0; j < col; j++)
       {
           if (i == j)
           {
               if (mat[i][j] != 0)//if element at diagonal is not 0 then return false
                   return false;
           }
       }
   return true;//other wise return truel
}
