That is, indexes of elements in right to left diagonal in the array are, n, n+(n-1), (2n-1)+(n-1) and so on till the index equals to 'length of the array - (n-1)'. The example 'c++' code is as follows: i==j and the sum of indexes of the right diagonal elements is one less than the size of the matrix i.e. Along the first diagonal of the matrix, row index = column index i.e mat[i][j] lies on the first diagonal if i = j. Here, we will read a matrix from the user and then find the sum of the right diagonal of the matrix and then print the matrix and sum of right diagonal on the console screen.. Create a matrix and define its elements. If the order is odd then subtract the middle number in the array from the final sum.
