Program: Benchmarking Buffered IO Buffered IO can be a time saver when your program is writing to a file $($or the terminal$)$ multiple times in quick succession. With each call of the write$(),$ the system call suspends your program. Buffered $10$ functions can save time by batching multiple prints into a single write to reduce the time your program is suspended. For today's lab, you will need to write two programs that write a string into a file $1$ million times using buffered and unbuffered IO functions. Your first program should use the open$()$ and write$()$ system calls. Your second program should use the fopen$()$ and fprintf$()$ functions from the standard library. You will need to use the time$()$ function that is part of the part of the standard library. You will need to record the

time before and after writing to the file $1$ million times. Your programs should output a message each time the write$()$ or print $()$ function is called and, in the end, output the time elapsed to write to the file $1$ million times to the terminal.
