I would like to know the difference and how to choose the polynomial generator for different crc ?
And in some C code they have look up table to compute crc and some of them do it by xor truth table. but in both the cases it is 1byte data array. Its confusing . Could somebody explain this as well ?
Thanks.!

I am facing a problem. The maximum binary number I am able to convert is 1000000000000000000. Is there any way to convert a binary number larger than this?
There is a function called strtoull (string to unsigned long long integer) which should work, follow the link for an example. https://en.cppreference.com/w/cpp/string/byte/strtoul

I would like to be able to convert a string such as "(5+6)*6" and get the resulting integer from that equation. It is important that it starts out as a string.
You can use library fastmathparser for c++.
In link is example how use this library.
If you really want write alone this parser, I recomended use Shunting-yard algorithm

So as part of RC6 encryption, the key size can be up to 256 bytes and operations are performed on the key throughout the encryption process. How do programmers store such huge values and perform operations on them? Specifically in C++?

I want to compare between two faces using openCV , how can I do that ?
Comparing between 2 images can be done by accessing each pixels and taking the difference or use the absolutedifference () to compare the two frames

I'm needing a elliptic filter code in c or c++, this code should filter a float input array.
Does anyone there have any code to do it?
Best
If you use e.g. MATLAB to design your filter (using e.g. the ellip function), you can take the resulting filter coefficients and very easily implement the filter in software (it's just a matter of multiplying the float values by the coefficients and following the rational filter equation).
