In this problem, you have to take two char arrays of numbers (e.g. 1203009954 and 109876201453) from the user and store each char array (number) in a separate integer array. While storing a number in an array you have to keep in mind that each digit of that number should be stored in a separate index (apply validation check (e.g. no alphabets or special characters (+_-)(*&^%$#@!~`;:,./? Etc) allowed)). You have to add these two numbers and store answer in a third array digit by digit.

Example: 1 2 0 3 0 0 9 9 5 4 1 0 9 8 7 6 2 0 1 4 2 3 + 1 1 1 0 7 9 2 1 1 3 7 7

Test case1: Marks 10 Input Num 1: 120367 Input Num 2: 1203a7 Output: Second number is invalid Test case2: Marks 10 Input Num 1: 1233677001257 Input Num 2: 1002 Output: 1233677002259 Test case3: Marks 10 Input Num 1: 109876201453 Input Num 2: 1203009954 Output: 111079211407 Note: 1. String and built in functions not allowed. 2. Use cin.getline for inputs. 3. Max size of arrays will be 20..

use c++ and do not use classes
