C++

A company wants to transmit data over the telephone, but they are concerned that the phones may be tapped. All of their data are transmitted as four-digit integers. They have asked you to write a program that encrypts their data so that it can be transmitted more securely.

1) Your Program should prompt the user and read the total number of data to be encrypted

2) Your program should read a four-digit integer (only one input) and encrypt it as follows: Replace each digit by (the sum of that digit plus 7 ) modulus 10. Then, swap the first digit with the third, swap the second digit with the fourth and print the encrypted integer.

NOTE: Comments and Indentations must be included in this program and future programs, if not, points will be deducted.

OUTPUT SAMPLE:
