break 'outer; } } } println!("Bye.");与loop 关联时,可以使用 break 表达式从该循环返回一个值。这仅对 loop 有效,对其他任何类型的循环均无效。如果未指定任何值,则 break; 返回()。循环中的每个 break 必须返回相同的类型。let (mut a, mut b) = (1, 1); let result = loop { if b > 10...

The inner loop will break when both i equals 1 and j equals 1. Therefore, the output will show values for i and j until that condition is met. This method is useful when you want to exit just one level of the loop while keeping the outer loop running....
Use break to Terminate a Nested for Loop in R In R, we can use the break statement to terminate a nested for loop prematurely. The break statement, when encountered, exits the innermost loop in which it is placed. This allows us to break out of both the inner and outer loops simultaneo...
In the above program, thebreakstatement is executed wheni == 2. It terminates the inner loop, and the control flow of the program moves to the outer loop. Hence, the value ofi = 2is never displayed in the output. Thebreakstatement is also used with theswitchstatement. To learn more, ...
There is another way break can be used (labeled form) to terminate the desired loop (can be an outer loop). How labeled break works? Label in Kotlin starts with an identifier which is followed by @. Here, test@ is a label marked at the outer while loop. Now, by using break with ...

We can use the labeled break statement to terminate the outermost loop as well. Working of the labeled break statement in Java As you can see in the above image, we have used thelabelidentifier to specify the outer loop. Now, notice how thebreakstatement is used (break label;). ...
JavaScript break With Nested Loop. Whenbreakis used inside two nested loops, it terminates the inner loop. For example, // nested for loops// outer loopfor(leti =1; i <=3; i++) {// inner loopfor(letj =1; j <=3; j++) {if(i ==2) {break; ...
