Question
Write a c
Program file1.c uses these:
(a) fork() to launch another process.
(b) exec() to replace the program driving this process, while supplying arguments to file2.c to complete its execution.
(c) wait() to complete the execution of the child process.
(d) file1.c takes two arguments x( a number less than 1) and n (number of terms to be added, 1 or more). For example: file1 0.5 5
(e) When the child process finishes, the parent prints: Parent(PID=yyy) : Done

- Write a short C program that declares and initializes (to any value you like) a double, an int, and a char. Next declare and initialize a pointer to each of the three variables. Your program should then print the address of, and value stored in, and the memory size (in bytes) of each of the six variables.arrow_forwardConsider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child…arrow_forwardWrite a MACRO in assembly language (NASM) with the name "CreateTitle" to capitalize the first letter of each word in a string stored in memory. The string ends with the character NULL (0). The macro requires 1 parameter, which is a memory address label containing the string to convert.arrow_forward
- Python script that uses the sys module to perform the following tasks:1. In a main method:a. Read and print the command-line arguments when the script is run.b. Print the Python path (the directories where Python is looking for modules toimport).c. Print the Python version.d. Print the platform name.2. The main() function must only run automatically if the module is being run directly, notwhen imported.arrow_forwardFor this C Program, I am getting the error "Expected an identifier" on line 18.arrow_forwardWrite a C/C++ program that performs the tasks described below. The program should fork one process. Have the new process execve theprogram named /bin/sed. Use dup2 (or dup) with a pipe to establish a wayfor the original process to capture stdout from sed. The program willaccept command-line arguments that it passes along to sed via execve.Any valid sed arguments may be used during testing.Sample executions are given below. Be sure to have this: alarm(90); as the first executable line in *BOTH* processes, which means you willneed to do it in at least one of the processes after the fork. Tests will be done by typing commands like this: ./p4 's/p/Z/g' TEMPIN The original process should capture stdout from sed and then print EACH lineprefixed by: SED:For correctness, it is important that EACH line have the prefix. For example, suppose that TEMPIN contains these lines: harry potter powerful wizard hermione played chess snape taught many pupils If the program is run as…arrow_forward
