When break is used inside two nested for loops, control comes out of which loop, the inner or the outer for loop? (I.e. does it break from all the present loops?)

by

It breaks from the inner loop only.

In C# (and in many other programming languages), when a break statement is encountered inside nested loops, it only breaks out of the innermost loop. The outer loop continues its iterations unaffected. So, the control comes out of the inner loop, not the outer loop.

Here’s a simple example to illustrate this:

csharp
for (int i = 0; i < 3; i++) {
Console.WriteLine("Outer loop: " + i);
for (int j = 0; j < 3; j++) {
Console.WriteLine("Inner loop: " + j);
if (j == 1) {
break; // This breaks only the inner loop
}
}
}

The output of this code will be:

mathematica
Outer loop: 0
Inner loop: 0
Inner loop: 1
Outer loop: 1
Inner loop: 0
Inner loop: 1
Outer loop: 2
Inner loop: 0
Inner loop: 1

As you can see, when break is encountered inside the inner loop, it breaks out of the inner loop only, and the outer loop continues its iterations.
