Q1) Including the initial parent process, how many processes are created by the program shown in Figure 1? Give an explanation for your answer. You can include an output statement to test and run the program. A sample output statement could be: printf("Testing......"); #include <stdio.h> #include <unistd.h> int main() { /*fork a child process*/ fork(); /*fork another child process*/ fork(); /*fork another child process*/ fork(); return 0; } Figure 1a - How many processes are created?

Write code that forks into two processes: a parent process, and a child process. Your code will be called with command-line arguments consisting of negative integers. Do not worry about bad command-line arguments such as "xyz". Your code will not be tested in this way. The parent process will take the arguments to main(), convert them into ints by calling atoi(), and send those ints one at a time to the child process through a pipe (one call to write()...
