Our focus is on introducing break and continue within a loop to derive a program hand in hand with its correctness. With break and continue so defined, we can naturally incorporate them into the well-known loop
首先说明:continue 只能用于循环语句中,而break可用于循环和switch语句,两者都是辅助循环;尽管如此,如果 switch 语句在一个循环中,continue便可作为 switch 语句的一部分;这种情况下,就像在其他循环中一样,continue 让程序跳出循环的剩余部分,包括 switch 语句的其他部分。 一般而言,程序进入循环后,在下一次循环测试之前...
ES.77: Minimize the use of break and continue in loops ES.77:循环中尽量少用break和continue Reason(原因) In a non-trivial loop body, it is easy to overlook a break or a continue. A break in a loop has a dramatically different meaning than a break in a switch-statement (and you can...
Python continue statement The continue statement is used to skip the rest of the code inside a loop for the current iteration only. Loop does not terminate but continues on with the next iteration. continue语句 这继续语句用于使用跳过对于当前遍历的循环里面剩余的代码。循环不终止,但是下一次循环继续。
for (i = 0; i < 10; i++) { if (i == 4) { continue; } printf("%d\n", i);} Try it Yourself » Break and Continue in While LoopYou can also use break and continue in while loops:Break Example int i = 0;while (i < 10) { if (i == 4) { break; } printf("%d...

Example 3: Using break and continue in a foreach Loop <?php// Using break in a foreach loop$numbers=[1,2,3,4,5];foreach($numbersas$number){if($number==3){break;}echo$number." ";}// Output: 1 2// Using continue in a foreach loop$numbers=[1,2,3,4,5];foreach($numbersa...
In the above example, numbers are printing after input but as we input-5, loop body terminated and program's control moves to next statement written after the loop body, which willprint"Bye, Bye..." C 'continue' statement Thecontinueis a statement, which is used to move program's contro...
1.breakbreak作用(在switch或 loop外部中断):1.break用于switch语句的作用是结束一个switch语句。2.break用于循环语句中的作用是结束当前所在的循环语句。2.continuecontinue和break有点类似,区别在于continue只是终止本次循环,接着还执行后面的循环,break则完全终止循环。 可以理解为continue是跳过 ...
#!/bin/bash for var1 in 1 2 3 do for var2 in 0 5 do if [ $var1 -eq 2 -a $var2 -eq 0 ] then break 2 else echo "$var1 $var2" fi done done如上,break 2 表示直接跳出外层循环。运行结果:1 0 1 5continue 命令continue 命令与 break 命令类似,只有一点差别,它不会跳出所有循环...
