# C Program to Find Sum of Diagonal elements in a Matrix2 min read

In this tutorial, we will learn how to write C Program to find the Sum of Diagonals of Matrix. as the matrix contains two diagonals, we will consider one as the main and another as the opposite.

Note that the number of rows and number of columns of a matrix must be equal that is it should be 2×2 or 3×3, etc. In other words, the matrix must be a square matrix.

We will look through the C program and find the sum of the main & opposite diagonal elements of an MxN Matrix. For example:

Consider a matrix of 2×2 matrix,
2    3
6    5
Output:
Sum of the main diagonals = 2+5 = 7
Sum of the opposite diagonals = 3+6 = 9

## C Program to find the sum of the diagonal elements in a matrix

Output:

As you can see in the program that if..else statement has been used to check if the order entered is a square matrix or not (`m == n`).
