Looping till infinity without breaking..

I would like to write a loop that counts until infinity, which may consist of a negative or a positive number.

Is this possible, please?

In other languages, I would probably loop till the size of an array with an undefined maximum size, however, how do I deal with the possibility of overflow?

for my $i (0 .. $#array) {
    for my $j (0 .. $#array) {
        next if $j == $i;
        # Compare $i, $j
    }
}

What does that have to do with .NET?
Looks like PHP to me...

Solution 1

There is no concept of infinity for integer types.
The best you could do is to put it in a while loop:

C#

int counter = 0;
while (true) {
   counter++;
}

But it will overflow at some point.

Infinity is very very long, especially near the end.
