What could be simpler and more pleasant than adding numbers? Especially for a robot. Let's write a program where the user enters numbers from the keyboard, and then a special method sums up the entered numbers. And does so until the user gets bored. When the user is bored, he or she enters -1: the program will understand that it's time to wrap things up, and will then display the sum on the screen.

I am completely lost with this exercise. So we're not taking the 5 user inputs listed? Is it random numbers? a = 14, sum = 0, sum += a is 14 or is a the sum of all numbers? If so, how?

while what is true though?? That's what I'm not 100% about. I got the code correct but I'm not sure what that condition satisfies.. how could it even be false??

Does the break make the condition "false" or simply make it exit?

/* but what if I input 5 lines of -1, does the question need us to stop at the 1st -1, or, need us to sum up the 5 lines of -1? */

Feel like I have done this one before? Did it reset somehow?

There seems to be confusion in the question. Conditions is if user enters -1 then program should stop taking inputs. Does it means that -1 should be added to the sum or it should be signal to stop the program and display the results of the numbers entered till -1 as an input provided.

The condition say "-1 should be included in the sum."

hint: (sum = sum + number) should be before the if statement

This one had me pulling my hair out for a bit until I realized you have to evaluate the keyboard input each time, not the running number that you keep adding to the previous number. After that it was fairly simple.

"-1 should be included in the sum" Didn't include it and got the solution wrong b/c of it.
