ALGO-145_蓝桥杯_算法训练_4-1打印下述图形

Posted 2020-10-31 WooKinson

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:

 1 #include <stdio.h>
 2 #define MAX 50
 3 
 4 int main(void)
 5 {
 6     int i,n;
 7     char arr[MAX+1];
 8     scanf("%d",&n);
 9     sprintf(arr,"%s","*");
10     for (i = 1 ; i <= n ; i ++)
11     {
12         printf("%*s%s%*s\\n",n-i,"",arr,n-i,"");
13         sprintf(arr,"%s%s",arr,"**");        
14     }        
15     
16     return 0;
17 }
