ALGO-145_蓝桥杯_算法训练_4-1打印下述图形

记:

这里用到了printf("%*s%s%*s\n",n-i,"",arr,n-i,"");的写法，

其中%*s中的*代表该字符串s的个数，s为给字符串，

这写法一般用在打印中

AC代码:

 #include <stdio.h>
 #define MAX 50

 int main(void)
 {
     int i,n;
     char arr[MAX+];
     scanf("%d",&n);
     sprintf(arr,"%s","*");
     for (i =  ; i <= n ; i ++)
     {
         printf("%*s%s%*s\n",n-i,"",arr,n-i,"");
         sprintf(arr,"%s%s",arr,"**");
     }        

     return ;
 }
