The example 'c++' code is as follows: For example, for a 2 x 2 matrix, the sum of diagonal elements of the matrix {1,2,3,4} will be equal to 5. Submitted by Nidhi, on November 02, 2020 . The left diagonal sum is more straightforward since the row and column indices of the diagonal elements in a square matrix are always the same. We can observer the properties any element A ij will diagonal element if and only if i = j. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array[i][k] where i is the index variable and k = array_length – 1. If you have a crazy idea and it works, it's really valuable. i+j == size-1. About Neeraj Mishra. Let’s take an example to understand it in a better way. second, which starts from the top-right corner and ends ar the bottom-left corner (let it be named as diagonal-2). Create a matrix and define its elements. C program to calculate sum of minor diagonal elements. Previous: Write a program in C to find sum of right diagonals of a matrix. By using two loops we traverse the entire matrix and calculate the sum across the diagonals of the matrix. > Find sum of all elements below diagonal in matrix in java > Find sum of both diagonals in matrix in java > Write a program - Find sum of upper triangle in matrix in java > Find sum of lower triangle in matrix in java > Write a program to - Display in required format in java. 2. This C program for sum of matrix diagonally opposite elements is the same as above, but this time we changed the algorithm a bit. 1. Diagonal of a matrix only exists if the matrix is a square matrix, So in this program you have to enter the order of square matrix for e.g. Then adds main diagonal of matrix as well as the opposite diagonal of the matrix. The simplest form of multidimensional array is the two-dimensional array. Simple C++ Program to add diagonal elements of a matrix and then print sum on the screen. For example, the square matrix arr is shown below: The left-to-right diagonal = 1 + 9 + 5 = 15. A crazy computer and programming lover.

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)'. Actually the values you used for filling your matrix are very badly chosen because you made a magic square, which is to say a 3×3 matrix whose diagonals and middle line and column sum up to the same value (15) so it does not prove it works at all.
