do-while语句和while语句类似,不同的是do语句先将循环体执行一次然后才判断条件表达式,以决定是否继续执行。本题中,执行 i=10-2=8后,执行判断i>6,结果为true。再执行i=8-2=6,然后再判断,6不大于6,则就不执行i-=2了。所以本题选C。 [解析]本题考查的是do-while语句。do-while语句和while语句类...
//continue 代码实例2#include<stdio.h>intmain(){int i=1;while(i<=10){i=i+1;if(i==5)continue;printf("%d ",i);}return0;} 代码输出:2 3 4 6 7 8 9 10 当i等于5时,continue语句会导致循环直接跳到下一次迭代,而不会执行printf语句。因此,这段代码会打印出2,3,4,6,7,8,9,10。当i...
(6)实现命令行提示符 break:跳出整个循环,不会再执行循环后续的内容 continue:跳出本次循环,continue后面的代码不再执行,但是还是会继续循环 exit():结束程序的运行 import os for i in range(1000): cmd = input(’[kiosk@test ~]$ ') if cmd: if cmd == ‘exit’: break else: print(‘run %s’ ...
当反复执行这个循环体的适合，需要在合适的适合把循环判断条件修改为false，从而结束循环，否则循环将一直...

1 2 3 4 6 7 8 9 10 总结: break在while循环中的作用: 其实在循环中只要遇到break,就停止后期的所有的循环,直接终止循环。 所以:while中的break是用于永久终止循环的。 continue介绍 //continue 代码实例1 #include <stdio.h> int main() { int i = 1; while(i<=10) { if(i == 5) continue; ...
