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.

You have an int array with n elements and a structure with three int members. ie struct No { unsigned int no1; unsigned int no2; unsigned int no3; }; Point1.Lets say 1 byte in the array element is represented like this - 1st 3 bits from LSB is one number, next 2 bits are 2nd no and last 3 bits are 3rd no. Now write a function, struct No* ExtractNos(unsigned int *, int count) which extracts each byte from array and converts LSByte in the order mentioned in point1.and save it the structure no1, no2, no3. in the function struct No* ExtractNos(unsigned int *, int count), first parameter points to the base address of array and second parameter says the no of elements in the array. For example: if your array LSB is Hex F7 then result no1 = 7, no2 = 2, no3 = 7. In the same way convert all the elements from the array and save the result in array of structure.
