Write a C++ program that prompts the user to input 4 integers A, B, C and D and then find the result of the Multiplication of the two leftmost digits from each number.

For Example: A=123 B= 23569 C=99 D=55689

Output: 12 * 23 * 99 * 55 = 1502820

Note: Each number must contain at least two digits. If any number has less than two digits the program must prompt the user to input it once again.
