OUTER_LOOP: for i := 0; i < 3; i++ { for j := 0; j < 3; j++ { if j == 1 { continue OUTER_LOOP // 跳过外层循环的当前迭代 } } } 3. 替代复杂的条件判断 简化多层嵌套中的控制逻辑。 避免滥用标签 过度使用goto或标签可能导致“面条代码”(Spaghetti Code),降低可读性。 保持代...
输出的结果是打印奇数,这是因为在for循环中存在条件选择,如果i变量的值的余数2等于零或i的值是偶数,则继续执行意味着继续 执行下一个循环,这样就不会输出i的值。 可以使用嵌套的for循环。 可以在此代码中看到嵌套的for循环用法示例。 packagemainimport"fmt"funcmain(){fori:=0;i<5;i++{//outer loopfmt.P...
line after for loop 1. 2. continue continue 语句用于跳过 for 循环的当前迭代。在 continue 语句之后,for 循环中出现的所有代码都不会在当前迭代中执行。循环将继续到下一个迭代。 让我们编写一个程序,使用 continue 打印从 1 到 10 的所有奇数 package main import ( "fmt" ) func main() { for i :...
But if you were to do much more, you should probably put that inner loop in a function and call it instead. You can then continue the outer loop based on the result. That will be cleaner code yet, and well-named functions make the intent of a block of code much more explicit. But...
// use break/continue on current loop // use break/continue with label on outer loop here: for i := 0; i for j := i + 1; j if i == 0 { continue here } fmt.Println(j) if j == 2 { break } } } there: for i := 0; i ...
In nested loops, break will terminate only the innermost loop. To break out of all loops, you can use a labeled break: </> Copy package main import "fmt" func main() { outer: for i := 1; i <= 3; i++ { for j := 1; j <= 3; j++ { if i == 2 && j == 2 { fm...
Outer Loop:Iterate through the list multiple times. Inner Loop:Compare each pair of adjacent elements. Swap Elements:If the first element is greater than the second, swap them. Repeat:Continue the process until no swaps are needed, indicating that the list is sorted. ...
In the program above, I have added abreakinside the innerforloop wheniandjare equal in line no. 10. This willbreakonly from the inner for loop and the outer loop will continue. This program will print. i = 0 , j = 1i = 0 , j = 2i = 0 , j = 3i = 1 , j = 1i = 2...
