Break in Julia

In Julia, the break statement is used to exit from a loop prematurely.

Here is a basic example of break statement used inside a for loop:

for i in 1:5
    if i == 3
        break
    end
    println(i)
end

Output:

1

2

In the above example, the for loop iterates from 1 to 5. However, when i becomes 3, the if condition is satisfied and the break statement is executed, causing the loop to terminate early.

Similarly, the break statement can also be used inside a while loop to exit prematurely. Here's an example:

i = 1
while true
    if i == 3
        break
    end
    println(i)
    i += 1
end

Output:

1

2

In the above example, the while loop runs infinitely until the if condition is satisfied and the break statement causes the loop to terminate.

It is worth noting that the break statement only terminates the innermost loop in which it is used. If break is used in a nested loop, it only terminates the loop in which it is used, while the outer loop(s) continue to run.
