思路：输出正方形即输出正方形的外围就行，外围有个特点就是行列下标必有0或者是正方形的大小减一，输入一个n表示正方形大小，输出一个由*组成的正方形。includestdio.hvoidmain(){intn，i；scanf(%d，&n)；/*输入个数n*/for(i=1；i=n；i++)printf(*)；/*循环输出字符*，若想修改显示格式...
if (x == 0 || y == 0 || x == num - 1 || y == num - 1) {//正方形的4条边,如果符合printf ("*");//打印*}else {//其他printf (" ");//打印空格}}}return 0;}另外一种方法:一行一行的输出1、输出n个*2、输出一个*,n-2个空格,一个*3、循环第二步n-2次4、输出n个* ...
