A company wants to transmit data over the telephone lines. All their data is transmitted as fourdigit integers. write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four digit number and encrypt as follows: replace each digit by the remainder after the sum of that digit plus 7 is divided by 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then print the encypted integer. Write a seperate program that inputs an encrypted fourdigit integer and decrypts it to form the original number

Best ResponseYou've already chosen the best response.0sample code for using a array to keep the numbers for easy reference. to interchange the values, keep the element in another symbol before assigning it away.
