What other ways can I write this loop?-CodePudding

I am still a beginner and I’m just wondering if my loop has any other ways I can write it for learning sake. Here is my loop:

    int count = 0;
    int index = 0;
    while(index >= 0 && index < arr.length && count < 100){
        index = arr[index];
        count  ;
    }

CodePudding user response：

you can use for loop for that mission, so you can write:

for (int count = 0, index = 0; index >= 0 && index < arr.length && count < 100 ;count  )
{
        index = arr[index];
}

but notice that in your for loop, you are not updating the value of index, by which I mean that index is always 0 even in your original code

A great alternative in this case would be a for loop. As you'll notice while coding when using multiple conditions to a loop it is best to use a for loop because it will look much neater and for loops already require three conditions perfect for your case.

    while ( condition && condition && condition) 
              vs 
      for ( condition ; condition ; condition)
