The # is the Pre-Processor. Means it is a special kind of
program that executed before the actual compilation of the
program. When it executed it performs several tasks like
defining etc. On such operation is the include. The include
tell that the current program requires certain inclusion of
files. Like #include<stdio.h>. Here we are directing the
pre-processor to include the stdio.h header file.

The purpose of this exercise is to benchmark file writing and reading speed. This exercise is divided into two parts. a). Write a file character by character such that the total file size becomes approximately >10K. After writing close the file handler, open a new stream and read the file character by character. Record both times. Execute this exercise at least 4 times b). Create a buffer capable of storing 100 characters. Now after generating the characters, first store them in the buffer. Once the buffer is filled up, store all the elements in the file. Repeat the process until the total file size becomes approximately >10K.While reading read a while line, store it in buffer and once buffer gets filled up, display the whole buffer. Repeat the exercise at least 4 times with different size of buffer (50, 100, 150 …). Records the times. c). Do an analysis of the differences in times and submit it in class.
