Exercise #1

Create a C program file called 'pipe.c' that does the following:

• Takes one command line parameter, an input filename.
• Creates a pipe(2) to communicate with a child process.
• Uses fork(2) to create a child process.
• Replaces the stdin of the child with the read end of the pipe.
• Replaces the stdout of the child so that it outputs to the file "output.txt".
• Execve(2)'s in the child the program /usr/games/ppt
• The parent process should then feed the contents of the input file (name given on the command line) to the child process using a read/write loop.
• The parent should finally wait for the child to complete using the waitpid(2) call.
