// 1. Both statements tell the program what to do and when to do so.
// 2. The if statement only checks one thing, and is executed only once, but the while loop continues checking until it is untrue.
// 3. Inside the while loop, there is no need for the "Int" because it was already clarified in the beginning of the program.
// 4. The deletion makes the program go on forever, because it has no terms to negate it.
