everyone. I have just started learning C++ and programming, and my exam task is about:
What does 'data type model' means? What kinds of 'data type models' do you know?
Actually, I can't find anything about it on the Web :(
There are many data types in c++:
int :integer numbers
double :real number
float: numbers with floating points
string : texts
char : characters
You can learn the details (and see where I got the image from) by visiting this website: http://en.cppreference.com/w/cpp/language/types

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

I've developed a MATLAB code that I think it is useful to be used by researchers. How can I embed it in a website to be used free?
It gets two integers and return a set of integers
Also it is possible to convert it to c++, If it helps.
Thanks
Submit your m-file(s) to Matlab Central File Exchange, this is the perfect place for it.

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.!
