Question

I would like to create a while loop where it will keep running under one of two conditions, where the one chosen is determined as a conditional. For example, it would be something along the lines of while(if (c = true) a<b else b<a). Is there any simple syntax for this? Or would I have to go the brute way and do the following?

if (c = true) 
{ 
   while(a<b)
   {
   }
} 
else 
{
   while(b<a)
   {
   }
}

Answer 1

You can take advantage of the short-circuit nature of boolean evaluations, and:

while ((c && a < b) || (!c && b < a)) {
    // ...
}

However, you might find this is difficult to read. Another approach might be to use the conditional operator:

while (c ? (a < b) : (b < a)) {
    // ...
}
