Hi, I'm not very good at english and I need help understanding c in this question. I understand the other two fine and I've already done the first one (which was to correct the formatting) and a little bit of the second one but I just wanted to understand the third one too thanks

I have provided pictures of my code so far so you know what is going on

Validate all the user inputs

#

That's creating probably a check for each user input

#

hmm

#

is that not in the code already

#

i think i figured it out, would it be adding an if/else statement before the guessing if/else-if statements indicating on whether its an integer or not

input validation means you need to check whether the inputs are correct

#

i.e. your program shouldn't allow invalid inputs

dusk merlin i.e. your program shouldn't allow invalid inputs

i think i got it

#

like i need to make sure its an int

#

the input

👍

dusk merlin Nov 30, 2023, 9:08 PM

#

for example

wintry isle Nov 30, 2023, 9:08 PM

#

hold on can i send my code i just need some advice

#

here is what i added, and here is the error message i get when i input a non integer but i want it to not consider the program to be finished yet so that it prints an error message and goes back to asking for an integer

#

could you let me know what i did wrong

dusk merlin Nov 30, 2023, 9:15 PM

#

well you are calling nextInt before hasNextInt

#

the nextInt can fail already

wintry isle Nov 30, 2023, 9:16 PM

#

dusk merlin well you are calling `nextInt` before `hasNextInt`

wait is that not what i do?

#

I was thinking that

#

it calls nextint but if nextint is not an int it would fail

dusk merlin Nov 30, 2023, 9:17 PM

#

wintry isle wait is that not what i do?

hasNextInt checks the next input

wintry isle Nov 30, 2023, 9:17 PM

#

yeah

#

uh

#

damn sorry im confused

wintry isle Nov 30, 2023, 11:03 PM
