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+1];
    scanf("%d",&n);
    sprintf(arr,"%s","*");
    for (i = 1 ; i <= n ; i ++)
    {
        printf("%*s%s%*s\n",n-i,"",arr,n-i,"");
        sprintf(arr,"%s%s",arr,"**");        
    }        
    
    return 0;
}
