I've never heard the term posneg before, but I'll assume it's a contraction of positive and negative, which is a signedvalue in C++, as opposed to an unsigned value which is always positive. Signed and unsigned are modifiers that can be applied to any integral data type (integer and char types).
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.
C++ is related to C, the language from which it is derived.
C++.
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.
3c
There is no such thing as 'unix C++'.
They do exist in C and C++.
C plus is between 3 and 3.2. C = 75% 0% < Plus < 5% 75%+0% < C Plus < 75%+5% 75 < C Plus < 80% 75%*4 < C Plus < 80% * 4 (3/4)*4 < C Plus < (4/5) * 4 3 < C Plus < 16/5 3 < C Plus < 3.2
Yes, you can rewrite a cuda program originally written in c in c plus plus.
No such thing.
