A credit card number must have between 13 and 16 digits. The starting numbers are: 4 for Visa cards, 5 for MasterCard cards, 37 for American Express cards, and 6 for Discover cards. + 6 * 2 = 12 (1 + 2-3) 5 2-10 (1+0-1) 8 2-16 (1 +6 7) Example: Validating 4388576018402626 a) Double every second digit from right to left. If doubling of a digit results |1 371449635398431 1s valid in a two-digit number, add the two digits to get a single digit number. 2 4444444444444448 1s valid b) Now add all single-digit numbers from Step a: c) Add all digits in the odd places from right to left in the card number: d) Sum the results from Step b and Step c e) If the result from Step d is divisible by 10, the card number is valid; 4 +4+8+2+3+1+7+8-37 6+6+0+8+0+7+8+3 38 37 + 38 # 75 3 4494424444444440 is valid 4 4110144110144115 valid 4114360123456785 is valid 6 4061724061724061 is valid 7 5500005555555559 is valid 8 5115915115915118 1s valid 9 5555555555555557 is valid 0 6011016011016011 is valid 11 372449635399431 is not valid 4444544444444448 not valid otherwise, it is invalid. 3 4444434444444440 is not valid Please implement Credit Card Number Validation: Function main is provided.
