Can Conditional Gotos Replace Nested Loop Exits?
A common question in programming is whether it's possible to use the break function to exit multiple nested for loops. While the answer is no, there is an alternative solution: conditional gotos.
In this approach, you can use a labeled goto statement to jump to a specific point in the code. This allows you to exit multiple loops based on a certain condition.
However, it's important to use conditional gotos with caution, as they can make code difficult to read and maintain. It's recommended to only use this approach when no other alternative is available.
One way to control how many loops the break exits is by using nested labels. For example, if you have two nested loops, you can use a label for each loop and then break to the outer label to exit both loops.
Here's an example of how this would work:
loop1: for i in range(10): for j in range(10): if i == 5 and j == 5: break loop1 print(i, j)
In this example, the break statement will exit both the inner and outer loops when i and j are both equal to 5.
