Here, it is reversing the array. Then adds main diagonal of matrix as well as the opposite diagonal of the matrix. The square matrix has two diagonals. Try to solve it here! 3. 1. In this reverse array in c program, When the compiler reaches to ArrayReverse (a, 0, Size – 1) line in the main() program, the compiler will immediately jump to the following function and executed the code inside that function. C++ language sample displays the nodes of a "Doubly Linked List" with the last C Language Program Print Reverse Array Print an array in reverse order, we shall know the length of the array in advance. Create a matrix and define its elements. second, which starts from the top-right corner and ends ar the bottom-left corner (let it be named as diagonal-2). 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.
