How to generate Circular Matrix

[meghs007]

Please help me to solv this program known circular matrix

input=3

output like

1 2 3
8 9 4
7 6 5

Well to solve this look a the matrix format... when we give an input the maximum number within the matrix is input square... that is if input is n then the maximum number feeded into the matrix will be n suqare.
Assume :
Array = a[][];
Input = n;
sq = n squared;

So take a variable num=0 and you have your input squared that is sq

while(num<sq)
{
// Coded for loops for traversal required,you may need upto 4 for //loops
}

Well, let's say you've declared a 2D matrix as the following: int matrix[n][n]; How would you write numbers around the border?

1  2  3  4  5
16          6
15          7
14          8
13 12 11 10 9

Now think of a circular matrix as a set of these rings, ever decreasing in size until the center of the matrix is reached. Once you've figured this out you'll have solved the problem.
