Objective:
Write a program to compute the CRC of a message using CRC-16 polynomial

Description:
	Here, Firstly this program will fetch data from file and stores it in to character array.
	It will pass the character array and length of the array to the crc function.
	In crc function, it will fetch the character and compute the CRC with shift and Ex-Or operations with CRC16, and return computed crc value to the main function
	That crc value will be converted into hexadecimal value and after converting into ASCII value it is appended at the last of the character string and passing into crc function again.
	And at last it shows crc 0.

 

Limitations:
	After fetching crc of the string, it gives value in Hexadecimal format.
	After converting into bytes, some values are out of 128 value which cant be converted into ASCII value, so it cant be appended into character string. So at last crc not returning 0.
