一:循环结构循环的概念：重复得做某一件事情举例：打印50份试卷沿操场跑10圈做100道编程题循环结构的特点：循环条件 （50，10,100）循环操作 （打印试卷，沿操场跑圈，做编程题）while 循环结构：语法：while(循环条件){循环操作}特点：先判断循环条件，再执行循环操作案例：实现打印50份试卷public class Demo01 {public static void main(String[] args) {//i:表示当前正在打印第几份试卷int i=1;while(i<=50){//循环操作System....

1.利用while循环计算1到100的和： 示例代码1： #!/bin/bashi=1sum=0while [ $i -le 100 ]do let sum=sum+$i let i++done echo $sum 示例代码2：利用while循环计算1到100之间所有奇数之和 #!/bin/bashi=1sum=0while [ $i -le 100 ]do let sum=sum+$i let i+=2done echo $sum 示例代码3：利用while循环计算1到100之间所有偶数之和 #!/bin/bashi=2sum=0while [ $i -le 100 ]do let sum=sum+$i let i+=2done echo $sum 2.利...
