Use C++ coding

program Credit Card Validator - Takes in a credit card number from a common credit card vendor (Visa, MasterCard, American Express, Discover) and validates it to make sure that it is a valid number (look into how credit cards use a checksum). -this is C++ program so use #include <iostream>. Also Please Use pointers, Arrays, and input/output files in the program

State whether the following are true or false. If false, explain why. a) Two pointers that point to different arrays cannot be compared meaningfully.

in C For each of the following, write a single statement that performs the indicated task. Assume that long integer variables value1 and value2 have been defined and that value1 has been initialized to 200000. a) Define the variable lPtr to be a pointer to an object of type long. b) Assign the address of variable value1 to pointer variable lPtr. c) Print the value of the object pointed to by lPtr. d) Assign the value of the object pointed to by lPtr to variable value2. e) Print the value of value2. f) Print the address of value1. g) Print the address stored in lPtr. Is the value printed the same as the address of value1?

Just answer directly without explaining. Thanks.
