请问一个200x200的二维数组怎么分成8x8小块的？

            #include<stdio.h>
             main(){
int a,b,c,d,e=0,f,z=8,h=0,i=0,j=0,l,m=0,n=0,o,a1[80][80],b1[100][100];

struct fjkdfe{
int eight[8][8];
}kk[100];
FILE *p;
p=fopen("e:\\gtt.txt","w+");
for(a=0;a<80;a++)
for(b=0;b<80;b++)
  {e++;a1[a][b]=e;}
  for(i=0;i<10;i++)
  {for(h=0;h<10;h++)
 { for(a=0;a<8;a++)
for(b=0;b<8;b++)
{ if(m==8)
{m=0;n++; printf("\n");fprintf(p,"\na"); }
if(n==8)
 {n=0;j++;}
(kk[j].eight[n][m])=(a1[a+z*i][b+z*h-1]);
printf("%d ",kk[j].eight[n][m]);
fprintf(p,"%d ",kk[j].eight[n][m]);
   m++;}

 printf("\n");fprintf(p,"\nb");  } printf("\n");fprintf(p,"\nc");  }
  for(a=0;a<8;a++)       /*输出一组看看  */
{{for(b=0;b<8;b++)
   printf("%d ",kk[0].eight[a][b]); }
     printf("\n"); }
     free(p);
getch();}
