Larry, Mary and Jerry get in a taxi.

They have different destinations, but all the destinations are right on the highway, so no circuitous driving is required.
Larry’s destination is 10 miles away, Mary’s is 20 miles, and Jerry's is 30 miles. The taxi costs $1.50 per mile.

How much should each person pay?

Taxi travels 30 miles, passengers travel for a combined distance of 60 miles. Hence if each pays half price per mile, the cost of the journey will be covered and each will pay in proportion to the distance he traveled.

The totality checker can easily miss something which would otherwise be total in a total language. It's garbage. It's merely a hack to allow for a slightly better Turing complete language.
Any why are you typing in this retarded manner?

Larry = ($1.50 / 3) * 10 = $5

Samefag here... I'm attempting to evaluate the following series (or rather, product)
PI/4 = ((2 * 4) * (4 * 6) * (6 * 8)...) / (3^2 * 5^2 * ...)

And I get the following error

. . num-prod: undefined;
 cannot use before initialization

When I run this:

(define (pi-approx n)
  (define (square x) (* x x))

  (define (num-prod ind) (* (* 2 ind) (* 2 (+ ind 1))))
  (define num (product num-prod 1 inc n))

  (define (denom-prod ind) (square (+ (* ind 2 ) 1)))
  (define denom (product denom-prod 1 inc n))

  (* 4 (/ num denom)))

Why is num-prod undefined when I clearly define it?

Would anybody welcome lambdas being introduced in the next C standard?

>>59879424
>lambdas
>C standard
why? just use Rust already jesus

>>59879419
Oh, I should probably mention, product is the following:

(define (product term a next b)
  (if (> a b) 1
      (* (term a) (product term (next a) next b))))

Basically, term and next are functions and [a b] represents the range of input values

>>59879424
anyone using C would probably stick to their dusty macros.

>>59879424
no

just allow plain old functions scoped inside a function like the GNU extension already has

>>59879342
With Jerry, even though he travels 30 miles, his actual fair should be that of 10. Larry can offer Jerry free ride until he reaches his destination since it does not cost him anything extra.

Larry has to pay $5 in this deal and Jerry has to pay 27.50, Mary has to pay more than $10 as well. 2 people are paying more. I don't think this deal would hold in real life. $15 each is still a fair deal.

>>59879417
Not if you're using the totality checker, which was implicitly assumed to be the case.

"in theory" jerry should pay more than larry to make it fair, otherwise larry doesn't have an incentive to give jerry a free ride and he can tell him to fuck off

>>59879461
The language itself is Turing complete (meaning it's trash), but a subset of it isn't.

>>59879488
lambdas are unnecessary neckbeard crap with shitty syntax. do a function definition with the plain old syntax and pass a function pointer instead of defining the function inline. only haskell-tier retards think it's good to have everything on one line

You guys probably assume im retarded for failing at a Object Oriented language but i could really use some help understanding what im doing wrong in this C# application.

Ive created a specification/inheritor class from the class Patient named PrivatePatient, it has its constructor that pulls from the normal Patient constructor and everything worked generally fine, however when i try and create a PrivatePatient object using the Patient constructor i get the error 'Patient' does not contain a constructor that takes 6 arguments.

Here is the code for the Patient constructor

       public Patient(String name, int age, String patientType, int hoursTreated)
        {
            this.name = name;
            this.age = age;
            assignedDoctor = null;
            this.setIdentifier();
            this.patientType = patientType;
            this.hoursTreated = hoursTreated;
        }

And here is the code for the PrivatePatient constructor

        public PrivatePatient(String name, int age, String patientType, int hoursTreated,
                              String privateHealthFundNo, String preferredDoctor) 
                       : base(name, age, patientType, hoursTreated)
        {
            this.preferredDoctor = preferredDoctor;
            this.privateHealthFundNo = privateHealthFundNo;
        }

Im sure its obvious to you guys but if you need more info i can post more.

That's quite personal and one that could be addressed if enough programmers cared.
>do a function definition with the plain old syntax and pass a function pointer instead of defining the function inline
But why do that when one could just use lambdas? It'd be easier.
>have everything on one line
Again, quite personal, and that can be addressed by line breaks if you dislike it so much.

>>59879557
Wanting C to have lambdas doesn't justify using very different languages.

listOfPatients is an ArrayList, but here you go

>>59879527
>shitty syntax
This is as retarded as saying "functions have syntax" or "loops have syntax".

>>59879701
>>59879712
it's objectively a different syntax compared to everything else in C. you would need a very compelling reason for it to be included in the C standard.

>>59879731
What syntax are you talking about? Are you really that fucking brain-dead to think that something has a fixed syntax?

>>59879709
haven't done c# in a while but shouldn't it be new PrivatePatient(...)?

>>59879650
>>59879709
It's because you are using 4 parameter patient constructor with 6 parameters.

Try using 4 parameters in constructor or create PrivatePatient object cast to Patient, like

this.listOfPatients.Insert(this.listOfPatients.Count, new PrivatePatient("Fred Bear", 29, "Private", 10, "HCF236788", "Ben Casey") as Patient);

Hi all! I would like to ask something about stuff I don't know and in a pretty basic level, but it could feel like I'm shitposting. May I ask it?

>>59879745
any syntax regardless of the specifics of the implementation would be different than what is currently in the C standard you disingenuous sperglord

I couldn't care less about the C standard. I'm just pointing out your blatant retardation.

>>59879731

>>59880319
If you want to get into machine learning in an academic setting the process would be something like this:

SAT placement 1400+
College placement into calculus 1 or higher, english 101 or higher
4-year undergraduate program (bachelor of science in computer science major)
apply to transfer to a good graduate school for CS majors like Cal Berkeley
Graduate program (Masters in CS, which includes getting a thesis relevant to your studies published)
Apply to whatever specialized college you want (probably Stanford, Cal Berkeley, or MIT)
Upper graduate program (Ph.D in CS which includes getting your dissertation (a book) published

All of this is going to cost you a shitload of money and basically you'll be in school the rest of your life.

Do you also support the reactive manifesto?

sepples question.
are member variables guaranteed to be initialized after the base class?
so eg.

struct A
{
    int x { 0 };
    A() { x = 1; };
};

struct B : public A
{
    int y { 1 / x };
    B() { };
};

this can never cause a division by zero?

Python evaluates the defaults for function arguments only once, when the function is defined. They get stored inside the function object and retrieved from there if the number of arguments is too small.

>>59881898
I think you come from tumblr based on the autism of your post.

I'm starting to do a basic interpreter, the goal is being able to write stuff like

>calculate the area of an square of 22 m

The idea is that it will look for "calculate", then "area", then "square" and finally look for an int/float number.

For that purpose I'm using the strstr function that allows me to look for an specific word inside an string.

#include <iostream>
#include <string.h>
#include <stdlib.h>
#include <windows.h>

using namespace std;

int ayuda(void);

int main(void)
{
    string command, aux;
    system("CLS");
    cout << "                                                          4chan\n                                                         " << endl;
    do
    {
        cout << ":::~ ";
        getline (cin, command);
        cout << "The command is " << command << endl;
        string aux (strstr(command,"help"));
        if (aux)
            cout << "Help was found";
    } while (command != "exit");
}

The problem here is that I can find any word BUT I can't make a conditional out of it, so let's say that if in the string there is the word "help", then it shows me the helping documentation.

g++ returns this

27:48: error: cannot convert 'std::__cxx11::string {aka std::__cxx11::basic_string<char>}' to 'const char*' for argument '1' to 'char* strstr(const char*, const char*)'
