Venting (somebody make it stop!)

:bawling: :bawling: :bawling:

I'm so sick of Microsoft Visual C++ that... that... I don't even know what. I have a huge lab due for my C class tomorrow, and it's about 75% done, and I just compiled it for the hell of it and it came back with like 50 errors. :banghead:

I still have to write a function to get the time and calculate the actual time, debug it, and test it. Plus write up a lab report of some kind. I have 10.5 hours, of which I'm going to need at least 5 to sleep. :werr:

Oh, and I just realized I have to check to make sure that the # of minutes entered doesn't exceed 59... :doh:

So, if any of you hear about some guy in California beating the crap out of his notebook tomorrow, you'll know why... :rolleyes2
Anyhow, I just had to get that off my chest... and here's the problem, if anyone is curious as to wtf I'm talking about:

I feel your pain on assignments. Damned Discrete Mathematics is going to be the death of me!

Here's an example...

2. (15 marks) A polynomial of a single variable x with integer coefficients is an expression of the form p(x) = c0 + c1x + c2x2 + � + cnxn, where ci, i = 0, 1, �, n, are integers. Denote the set of such polynomials by P.

The following is a recursive definition of a set Q:
(*) c � Q, if c is an integer;
(**) c + xq � Q, if q � Q, and c is a integer.

(i) (1 mark) Justify that f(x) = x - 2x2 + 3x4 � Q.

(ii) (6 marks) Show that P = Q. In other words, P can be defined recursively by rules (*) and (**).

(iii) (4 marks) Use the recursive definition of P to prove the following result by mathematical induction:

Suppose a and b are integers, a � b (mod m), and p(x) � P is a polynomial. Then p(a) � p(b) (mod m).

(iv) (4 marks) Use the recursive definition of P to develop a recursive algorithm to find the value of p(x) = c0 + c1x + c2x2 + � + cnxn, if x = a is an integer.

It hurts the brain!!!! :eek3: :eek3: :eek3:

No! Make it go away! Math BAD! Math EEEEEVILLLLL!!! I can't stand math...

[Clutch]

I swear..math is the root of all evil...

[t1rhino]

Do you mean the square root? :D

��evil = math :)

BTW, C++ is a biotch... The only language where fixing 1 error can cause 99 more errors...


/edit: vbforums can't display certain special characters. :(

I used to hate math too. But as I got older I realized how much it fits into daily life. Now I like to do math and if I have the time try not to use a calculator. It seems to be one of the best execises for your brain. Just give it 10 years or more! ;)

[maxanon]

Ahh, this reminds me of the good old days of school. Man I miss those days.

[Geeky1]

t1, this isn't C++ (thankfully)... this is just ANSI C... and fixing 1 error generally only causes 50 new errors in C...

[Enverex]

t1rhino: Try using the code option (or PHP option) it should display it properly.

If you're using C++ then use std:cin and std:cout.

You're going to have integers for hours and minutes . . . possibly seconds.


unsigned int hours, mins, secs;
hours = mins = secs = 99;

do {
cout << "Enter hours: "
cin >> hours;
} while (hours > 23);

do {
cout << "Enter minutes: "
cin >> mins;
} while (minutes > 60);

// You get the idea.



by my estimation you have about 2 hours before your assignment is due. If you see this in time and have some questions about specifics just ask . . . I'll try to check the page as often as I can.

I loved Discrete Math....it was just like my digital logic class.

[Swettacular]

wow, I had to do almost that exact same assignment in my C++ class, but we didn't have to check for correct times and the input was from a file not a user, and we weren't allowed to use functions

[TheBaron]

ha SimGuy, i'm taking that class next semester :)

along with differential equations and linear algebra, YAY!

TheBaron had this to say

I bombed all 3 of them last year @ the University level. :)

Evidently, advanced multi-variable differentiation calculus, technical algebra & discrete logic mathematics aren't my fort�.

Although I've still got all the assignments and solutions for those courses.... :hrm:

[Geeky1]

a2j, thanks... I didn't see it in time, unfortunately, but I got it done... stupid 250 lines of code... grr...
