Here is the C program to find sum of diagonal of a square matrix. 3. 1. The square matrix has two diagonals. Sum of 1st diagonal is 15. 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. Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. 2) The main() function calls the sumofarray() function by passing an array, size of an array. Below statements ask the User to enter the Matrix size (Number of rows and columns. Write a program in C to find the sum of rows an columns of a Matrix. Using Function. So why we are waiting, let's do it firstly, we have to find the right diagonal sum of a matrix and left a diagonal sum of magic, then we will find out the Diagonal Difference of a matrix. "; getch();}-----IMPORTANT POINTS ABOUT THE PROGRAM : 1. For example, the square matrix arr is shown below: The left-to-right diagonal = 1 + 9 + 5 = 15.

Then adds main diagonal of matrix as well as the opposite diagonal of the matrix. This C program for sum of matrix diagonally opposite elements is the same as above, but this time we changed the algorithm a bit. Contribute your code and comments through Disqus. 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. Declare two variables which will store sum of main and opposite diagonal. Using this code we find the sum of diagonal elements of a square matrix.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. 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. The right to left diagonal = 3 + 9 + 5 = 17.
