题目：打印出所有的“水仙花数”，所谓“水仙花数”是指一个三位数，其各位数字立方和等于该数 本身。例如：153是一个“水仙花数”，因为153=1的三次方＋5的三次方＋3的三次方。1.程序分析：利用for循环控制100-999个数，每个数分解出个位，十位，百位。2.程序源代码： 1 #include<stdio.h> 2 int main() 3 { int i,j,k,n; 4 printf("water flower number is:\n"); 5 for(n=100;n<1000;n++) 6 { i=n/100; /*分解出百位*/ 7 k=n/1 阅读全文

题目：打印楼梯，同时在楼梯上方打印两个笑脸。 1.程序分析：用i控制行，j来控制列，j根据i的变化来控制输出黑方格的个数。2.程序源代码： 1 #include<stdio.h> 2 int main() 3 { int i,j; 4 printf("\1\1\n"); //打印两个笑脸 5 for(i=1;i<11;i++) 6 { for(j=1;j<i;j++) 7 printf("%c%c",23,23); //23这个数字可以是任意数，代表该数所对应的符号 8 printf("\n"); 9 }10 阅读全文
