Answer 1

You're getting the logical result you describe, but it wasn't what you expect. Specifically, when either of your conditions evaluates to false the logical and will not evaluate to true. I think you wanted

while (!(diceRolled1 == 5 && diceRolled2 == 4)) {

which is while not dice1 equal to 5 and dice2 equal to 4. And then, using De Morgan's Laws that might also be expressed as

while (diceRolled1 != 5 || diceRolled2 != 4) {

which means loop while dice1 is not equal to 5 or dice2 is not equal to 4.
