This program prints the numbers in a given 2D array (matrix) in spiral order. It takes the order of the matrix as input, stores the numbers in the matrix by scanning row-wise, and then prints the numbers by traversing the matrix in a spiral pattern starting from the top left corner, moving right, then down, left, and up. It uses a while loop to iterate through all elements of the matrix until all numbers are printed.

1. This Program prints the numbers in given array(Row-Major Order)in Spiral order. Ex: Order Is 3*4 11 12 13 1415 16 17 1819 20 21 2223 24 25 26Spiral Order Of Matrix is 11 12 13 14 18 22 26 25 24 23 19 15 16 17 21 20<br /># include<stdio.h><br />main()<br />{<br />int a[20][20],i,j,n,m,p,q,k=0;<br />printf(\"
