Write a shell that contains enough code that it actually works so you can test it. You might also add some features such as redirection of input and

output, pipes, and background jobs. Use C++ language to answer this question.

#define TRUE 1

while (TRUE) { /* repeat forever */

type prompt( ); /* display prompt on the screen */

read command(command, parameters); /* read input from terminal */

if (for k( ) != 0){ /* fork off child process */

/* Parent code. */

waitpid(1, &status, 0); /* wait for child to exit */

}else {

/* Child code. */

execve(command, parameters, 0); /* execute command */

}

}
