This is the code I have tried and it only works with 3 digits numbers but the sum does not exceed 1000 for adding 3 digit numbers that exceeds 1000 just outputs 1000. I also have a problem fixing adding 1 and 2 digit numbers as inputting 1 and 2 digits numbers results in invalid character. I am confused and been working with this code for 6 hours now and still haven’t fixed it.
