Create and print a magic phalanx of 1 to n^2 natural numbers

#include "stdio.h"
void Main (void)
{
int a[15][15]={0};
int i,j,k,n,p=1;

while (p==1)//parameter p is set to determine N input range
{
printf ("Please enter an odd n (1 to 15):");
scanf ("%d", &n);
if ((n>0) && (n<=15) && (n%2!=0))//The Order of the magic square should be odd, even for the time being not oh ~ ~ Hehe
p = =;

Build the Magic Phalanx.
J=N/2;
A[0][j]=1; Put "1" in the middle of the first row.

if (i<0)

j=0;
A[i][j]=k;
if (k%n==0)//When the number inserted is an integer multiple of n, the next starting point is set to the next line in his column
