用c语言编写的小c程序实现一级一级的输出

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
#include"stdio.h"
#define N 9
main()
{int a b c;
 for(a=1;a<=N;a++)
    for(b=1;b<=2*a-1;b++)
        { if(b<=a)
            printf("%d",b);
           else
             printf("%d",2*a-b-1);
           }
 printf("\n");
  }


#include"stdio.h" 
#define N 9 
main() 
{ 
int a,b,c,d,e; 
for(a=1,d=0,c=N;a<=N;a++,d++,c--) 
{ 
for(b=1,e=1;b<=d+N;b++) 
{ 
if(b<c) 
printf(" "); 
 if(b<=d) 
       printf("%d",e++); %e should be substanted by b;
    else 
       printf("%d",a--); 
 };
 printf("\n"); 
}; 
}
