Object Oriented Programming.
Although some people, myself included, consider OO to be a state of mind rather than a specific language implementation, and that you can use OO principles in non OO languages, even assembler, but the above answer is generally accepted as true.
It has no meaning in C++. The name "cant" is undefined and there is no "std::cant" name defined by the C++ standard library. It's most-likely a user-defined name, but without seeing the definition or context in which it used it's impossible to say what its meaning is. In all likelihood it's a constant Boolean value, where can is true and cant is false (or vice versa depending on the logic of its usage).
I see no reason why you can't do that. The question must be mis stated. Please clarify, and show your code.
C: there are no methods in C. C++: no.
c is procedure oriented and c++ is object oriented & much newer.
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
A discriminant that is less than zero.

b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
4c
c + c + c + c + c = 5 * c.
There are no "primary and secondary keys" in c and c plus plus.
