Write a C/C++ code to implement the CSMA/CD algorithm. Your program output should demonstrate the contention of 10 stations to gain access on a shared bus using ersistent gorithm with binary nential backoff) as follows: Step1: If the medium is idle, transmit; otherwise, go to step 2 Step2: If the medium is busy, continue to listen until the channel is idle, then transmit immediately Step3: If a collision is detected, transmit a brief jamming signal to assure that all stations know that there has been a collision and cease transmission Step4: After transmitting the jamming signal, wait a random amount of time, referred to as the backoff, then attempt to transmit again.

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: a. double the number. b. reverse the digits of the number. c. raise the number to the power of 2, 3, or 4. d. sum the digits of the number. e. if the number is a two-digit number, then raise the first digit to the power of the second digit. f. if the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. after performing an operation if the number is less than 10, add 10 to the number. also, after each operation determine if the number is prime. each successive operation should be performed on the number generated by the last operation. your program should not contain any global variables and each of these operations must be implemented by a separate function. also, your program should be menu driven. 7.
