Task $2$: read

Write a small C program that opens a file $(/$usr$/$lib$/$locale$/$locale$-$archive on the department servers is a reasonable choice due to its size; though it is rather small by today's standards$)$ and reads the contents of that file using the read system call. Write this code in a manner that allows you to easily change the number of bytes read $($use a #define for the array size and argument to read$).$

Your program must not print anything $($doing so will skew the timings discussed below$).$

Run this program with sizes $1,2,16,32,64,128,256,512,1024,2048,4096,$ and $8192($yes$,$ all of these; it shouldn't take that long$)$ and record the running time with the time program on the command$-$line $($e$.$g$.,$ at the prompt, type time $./$a$.$ out and record the "real" time$).$ Plot the results; can you infer any characteristics about the system?

Task $3$: fread

Copy your program from above and modify it to use the fread library function in place of the read system call $($and fopen instead of open$).$

Run the program with the same sizes and above and plot the execution times.
