Write a C program that meets the requirement in Programming Problem 3.21 in the textbook. In addition, your program should also display the process IDs of both the parent and child processes. Follow the code in Figure 3.34 to print the process IDs.

3.21 The Collatz conjecture concerns what happens when we take any positive integer n and apply the following algorithm: n = I n/2, | 3 x n +1, if n is even if n is odd The conjecture states that when this algorithm is continually applied, all positive integers will eventually reach 1. For example, if n = 35, the sequence is 35, 106,53, 160, 80, 40, 20, 10,5, 16, 8, 4, 2,1 Write a C program using the fork() system call that generates this sequence in the child process. The starting number will be provided from the command line. For example, if 8 is passed as a parameter on the command line, the child process will output 8, 4, 2, 1. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a positive integer is passed on the command line. #include #include #include int main() pid.t pid, pid1; /* fork a child process */ pid = fork(); if (pid #include #include int main() pid.t pid, pid1; /* fork a child process */ pid = fork(); if (pid
