自己编的魔方阵程序

#include<stdio.h>
#define MAX 30
int square[MAX][MAX];
int N;
void magic();
void main()
{
    int i,j;
    do
    {
         printf("please enter odd matrix size:");
         scanf("%d",&N);
         if(N%2==0||N<=0||N>30)
             printf("should be>0 and<30 odd number");
         else
             break;
    }while(1);
    magic();
    printf("\nthe %d*%d magic matrix\n",N,N);
    printf("__________________________________\n");
    for(i=0;i<N;i++)
    {
        for(j=0;j<N;j++)
            printf("%5d",square[i][j]);
        printf("\n");
    }
    printf("__________________________________\n");
}
void magic()
{
    int i,j,p,q,key;
    for(i=0;i<N;i++)
        for(j=0;j<N;j++)
            square[i][j]=0;
        square[0][(N-1)/2]=1;
        i=0;
        j=(N-1)/2;
        key=2;
        while(key<=N*N)
        {
            p=i-1;
            q=j-1;
            if(p<0) p=N-1;
            if(q<0) q=N-1;
            if(square[p][q]!=0)
                i=i+1;
            else
            {
                i=p;
                j=q;
            }
            square[i][j]=key;
            key++;
        }
}

什么叫魔方阵啊？
----------------解决方案--------------------------------------------------------
我是新手
是不是每个程序都要加预处理命令啊
----------------解决方案--------------------------------------------------------

预处理？什么意思？
