Question

Is there a mathematical way to do what this C program does

Answer 1

#define close_enough 0.01

main()
{
char facts[] = {"fat (grams)", "calcium (%)", "carbs (grams)", "vitamin D (%)", "cholesterol (%)" };

double ingred[3][5] =
{
{ 0, 1, 2, 4, 3 },
{ 3, 4, 5, 0, 3 },
{ 0, 6, 0, 7, 8 }
};

int numbers_should_equal_this[] = { 15, 43, 4, 7 ,3};

int looper[3];

for (looper[0] = 0 ; looper[0] < 100 ; looper[0]++)
for (looper[1] = 0; looper[1] < 100 - looper[0]; looper[1]++)
for (looper[2] = 0; looper[2] < 100 - (looper[0] + looper[1]) ; looper[2]++)
if (ingred[0][0] * (looper[0] / 100.0) < close_enough)
if (inged[1][0] * (looper[1] / 100.0) < close_enough)
if (sugar[2][0] * (looper[1] / 100.0) < close_enough)

Answer 2

:) it is not complete, but you get the idea

Answer 3

What is it meant to do?

Answer 4

You do have a mathematical way to do this - it's your algorithm.

Answer 5

this is not complete but complicated

Answer 6

I'm closing my eyes. I had a test yesterday in Object Oriented Programming ._.

Answer 7

it will figure out what ratios of ingredients are needed for a given food. For example I have a cheesecake snack which contains only cream cheese, sour cream, sugar and eggs. I know from the box the nutritional facts of the box, and I know the nutritional facts about each ingredient. Now with this information I should be able to figure out the ratios with a program that just tries every possibility and checks to see if the numbers work.

Answer 8

simple

Answer 9

OOP is cool but this is not OPP

Answer 10

noticed.

Answer 11

is this linear programming?

Answer 12

you guys should see my 24000 lines C++ code LOL

Answer 13

programming scares me

Answer 14

I guess it is procedural programming, not linear, IMHO

Answer 15

programming is easier than most ppl think

Answer 16

lol angoo, I do practice programming, but I don't go deep into it.

Answer 17

my programs never work properly and i have no patience and just get angry

Answer 18

what language do you use loki

Answer 19

LOL , let me guess, error error unable to complie LOL

Answer 20

some random crap

Answer 21

which language do you use? Java, C++? C? C# etc etc

Answer 22

i used C program with bloodshed dev c++

Answer 23

you can learn enough of programming to make a simple text based role playing game in about a month

Answer 24

I don't know. I was forced to do some as part of my degree. C or something.

Answer 25

I use Java , since it's the only language available to practice here in campus

Answer 26

YEY!!!
I also used to use Bloodshed

Answer 27

Yeah, you're all nerds...

Answer 28

lol =D

Answer 29

I ain't a nerd, you should see me in real life LOL, you would be surprised

Answer 30

I know you are kidding, so am I

Answer 31

there's a difference between a nerd and a geek, geek = computer more person, nerd = study more person lol

Answer 32

to make a mathematical program from complicated case, u have to learn linear programming, i think.

Answer 33

no need

Answer 34

so you're saying if i saw you, i *would* think you were a nerd?

Answer 35

I was so proud of the program I wrote lol, finding the factorial of a number >_<

Answer 36

it took me AGES ._.

Answer 37

no, you would not, not a chance, everyone is surprised when I tell them I am into computers and geek stuff

Answer 38

they think I am a bodybuilder or something

Answer 39

kidding, no, in real life you it is quite easy to see I am into TECH

Answer 40

in the end noone can solve ur algorithm lol

Answer 41

lol, in other words , a geek with a pretty smile =D I guess?

Answer 42

=D

Answer 43

I am just trying to confuse you all

Answer 44

LOL =D

Answer 45

not working here ^_^

Answer 46

Yeah, I'm confused.

Answer 47

LOL!

Answer 48

hahaha

Answer 49

then angoo striked one person, he's what do you call that thing, um, socializing thingy?

Answer 50

so guys, anyone wants C++ lessons? *eating a bannana*

Answer 51

BMF u made a HERO confused, well done

Answer 52

he has done it before lol

Answer 53

loki is drunk ~

Answer 54

bananas get you excited LOL

Answer 55

I never want to see C++ or any C again

Answer 56

I have never even seen C++ or C

Answer 57

i want to see A always

Answer 58

If I can't do it with pen and paper or on excel, i get someone to write up a program

Answer 59

C++ is very simmilar to java

Answer 60

try try try again and again

Answer 61

that's what I've heard andy

Answer 62

but they say C++ is alot more easier than Java

Answer 63

my problem is that it's so finicky. so much room for error. one mistake and you can spend hours looking for it.

Answer 64

and, no, bananas do NOT get me excited, they are just fruit

Answer 65

lol, they get you excited :)

Answer 66

nah, java and C++ are exactly of same difficulty

Answer 67

ahh outta topic

Answer 68

they have a very long-named chemical that I don't remember that gives you energy ^_^ same thing with chocolate and barely. I forgot the name hmm wait

Answer 69

just that, java is used for one thing, and C++ in other situations

Answer 70

Oh yeah, Tryptophan! :) that's what it's called

Answer 71

Tryptophan puts you to sleep!

Answer 72

banana , choco, and barely = goog for heart = because they contain serotonin.

Answer 73

it's in turkey

Answer 74

lol, it's in bananas, chocolate and barely lol

Answer 75

I have attended an Organic Chemistry course for fun ^_^

Answer 76

Java:
-Finances
-Web
-Simple boring games

C++
-Operating Systems
-Almost all comercial software
-Bank server software
-Airplane software
-3D games (like for PS3, PC...)

Answer 77

but they're using java now

Answer 78

who?

Answer 79

folks, all of u get a job, someone asking about max domain

Answer 80

everyone

Answer 81

I'm not sure of the maximal domain >_<

Answer 82

nope, not everyone, java is great for smal programs, C++ is good for complex comercial ones, the multimilion ones

Answer 83

They've stopped teaching C++ though

Answer 84

do you know why?
because with java it is easyer to make simple programs and dysplay simple graphics, which is good for learning, but C++ can take very long time to learn, just to draw a cube on the screen is hard

Answer 85

They say that in computer engineering, C++ will be taught and Java will be ignored.

Answer 86

anyways, languages are languages, all function the same in the end.

Answer 87

all have one place to go, all have same use.

Answer 88

stupid computer with some human intelligence

Answer 89

obedient to the rules.

Answer 90

etc.

Answer 91

check this, it has a simple C++ program with two 3D objects spinning aroun, AND a cpp file with the SOURCE CODe

Answer 92

so finaly you can see how C++ looks and how much code you need to do that simple stuff

Answer 93

I'll check it later , thanks

Answer 94

I guess

Answer 95

oh, and check this, it is more fun#
=D

Answer 96

:)

Answer 97

will do
