sort of homework help, sort of not
the main problem is I don't understand what she wants this code to do
and there's so little code actually in the question

DC.f takes char[], but bitch is giving her a float.

Every non-trivial class needs a constructor and destructor method.

>> No.2009042

in the class definition for DC, f is defined to take char; but when implemented in main, she plugs in rounded pi, which is a double not a char

>> No.2009069

Overload the .f( ) function and make it a template.

Doesn't C++ allow multiple functions with the same name as long as their parameters are different? If so there's nothing I see wrong here.

at first glance i thought virtual that BC function, but then i thought cus it's overloaded it doesn't matter.

Now i'mconfused cus DC inherits BC functions and i think that code should work...

Someone explain to me how i am wrong plase?

I guess if they're really cheap and want to buy a 16k chip for their Integrated circuits
Need to do something very specific that would benefit from the extra speed
or want to get the most bang out of their buck for their super computers
or if you want to write a computer virus
oooor if you want to hack an encrypted application
No sane person would program anything in assembly from scratch though
only small things

>> No.2009279

I mostly agree, however
>guided missile
pretty sure they spend enough money on each one that they wouldn't mind dropping another $25 on a ~2.2ghz intel/AMD chip that's newer than Pentium 5

by then we would have applications that would need that speed, and utilize it to its FULLEST power.

Just admit you knew what I meant, and are just being a faggot.

>> No.2009472

Assembly is also commonly used under the hood like in real time applications to do something like draw the courser on your screen or control your anti lock breaks or modulate the signals coming out of your cellphone. A good programmer can wright assembly knowing the timing of execution to the clock cycle. Besides it's just so much fun to reach up under a computers skirt and fiddle with her registers.

Math made up. It is true because it is defined to be true. It just happens to be useful when describing the world..
