    while loop question

    If I had the following while loop:

    Code:
    int count = 0;
    cin >> value;
    while (value < 0 && count < 5)
    {
         cout <<"Value must be non-negative;"
         <<"enter value again. " <<endl;
         cin >>value;
         count++;
    }
    What would the value of count after the loop is executed with the following data keyed in:

    -1
    -2
    -1
    0
    3


    --Would it be 3, b/c when it enters 0 then it jumps out?

    thanks

    The simple answer would be to compile it and run it
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    It is 3. That in my opinion is really poor programming though as it's going to increase the count even after you enter 0. In glancing over it you expect it to STOP counting when the value is not less than 0 but it counts one more. I would suggest the do while loop.
