对比下,C语言中跟repeat..until语句等价的是do..while语句,是支持continue的。这是因为C语言的do..while语句中,while后面的条件判断是在内部代码块的作用域之外的。比如下面代码就会编译错误: do { bool ok = request_xx(); } while (ok); // error: ‘ok’ undeclared 这样的规范(条件判断是在内部代码块...
Break and Continue in While Loop You can also usebreakandcontinuein while loops: Break Example inti =0; while(i <10) { cout << i <<"\n"; i++; if(i ==4) { break; } } Try it Yourself » Continue Example inti =0;
首先看continue,Enter loop,循环开始,然后是循环的测试条件,如果为假,则直接跳出循环;如果为真,就到了continue,判断continue的真假,如果为真,循环返回开始的测试条件,跳出当前循环步骤,继续下一个循环,如果为假则循环继续执行剩下的语句。 2.break语句 Enter loop,循环开始,循环开始的测试条件,如果为假,循环结束;如...
c 语言中循环语句有 3 种:while();do while();for;且 3 种循环都可以使用 continue 和 break 语句对于continue语句,执行到该语句时,会跳过本次迭代的剩余部分,并开始下一轮迭代;但是若 continue 语句在嵌套循环的内部,则只会影响包含该语句(即 continue 语句)的内层循环(即内层循环的后面的语句不会被执行,而...
在循环语句中,下面哪种语句的作用是提前进入下一次循环( ) A. continue B. break C. if D. loop 相关知识点: 试题来源: 解析 A 【详解】 本题考查循环控制。在循环语句中,continue 语句的作用是提前进入下一次循环,跳过当前循环中 continue 语句之后的剩余代码。故答案为A选项。反馈 收藏 ...
In a while loop, the loop will continue as long as the condition is: A. True B. False C. Equal to zero D. Not E. qual to zero 相关知识点: 试题来源: 解析 A。在 while 循环中,只要条件为真(True),循环就会继续执行。如果条件为假(False),循环结束。反馈 收藏 ...
while循环语句后面多了个分号 导致 编译器认为continue不在循环的内部 把分号删掉即可
The `continue` statement can be used in the following loop structures: `for` loops. `while` loops. `do...while` loops. For example, the following `for` loop skips the even numbers and prints only the odd numbers: c. for (int i = 0; i < 10; i++) {。 if (i % 2 == 0)...
while ( i < 20 ) { i++; if ( i == 10) break; } return 0; } In the example above, the while loop will run, as long i is smaller then twenty. In the while loop there is an if statement that states that if i equals ten the while loop must stop (break). ...
