I'm currently writing a CRC16 program which computes the CRC of characters using the CRC 16 polynomial X^16 + X^15 + X^2 + 1. The program should read data from the. A cycle redundancy check (CRC) in C programming is an error detecting commonly used in storage devices, etc. Block of data is entered and is checked and it is based on if the remainder is 0 or not and if it not found to be zero then an error is detected in the code. CRCs are popular because they are simple to implement in binary hardware. CRCs basically are used as xor operation is performed between two numbers if remainder is zero then no error if it’s not zero then error is detected. We start our code by including the header files “stdio.h” and “conio.h”. Then we input the first number (dividend) in array n[] usually the larger number and in this example a 8 digit number Which is “10100001” and then the second number in array div[] if entered usually a smaller than the first number (divisor) in this example a 4 digit “1001”, after input of both the numbers few zeros(0) are added at the end of the first array(n[]) and the number of zeros are equal to the number of digits in divisor-1. For example if digits in divisor are 4 then 3 zeros will be added at the end of dividend. Take advantage of our limited time offer and gain access to unlimited downloads for FREE!

Variable “temp” is used instead of “i” to avoid confusion as the value of I has to be changed in the second for loop. For this program I have already given a fixed input of fixed number of digits to be entered but you can ask the user too. The program is really simple you just need to understand the logic.
