How do I get started of building actual programs?

Inheritance style of program building leads to a lot of awkward hierarchies and the worst of all, "class relationships"
Compositional style tends to deliver programs that are easier to reason about
answer this easy question stupid shitters
if a float type has a magnitude range of (2^-62, 2^62) and can accurately represent all integers between -2^16 and 2^16, then can it represent e.g. (14.125 + 1.0/(2^10)) with full accuracy? and a float type with a magnitude range of (2^-14,2^14) and an integer range of (-2^10,2^10) can not?

I'm interested in collision detection.
Let's say my player moves at 5px at a time in a 2d plane. there's a wall 3px away from him. I want him to be flush up against the wall, so could I get the distance between him and the nearest wall, and then have him move that distance (3px)? How would this work for a tile diagonally away from the player?
Also, how can I detect collision without checking every single tile in the entire map? I was thinking of having a few quadrants of maybe like 25 tiles at a time, or maybe I could have it check on the tiles visible on screen?
I'm new to this. Any direction would be appreciated

Learn about it, but don't get stuck at it, unless you want to be mediocre. OOP really only addresses one side of the expression problem. Do FP, too.

In C, it is well defined to cast a function pointer to any type. It's just undefined behaviour to call a the function pointer if the function signature doesn't match the pointed-to function.
Where is a somewhat contrived example:#include <stdio.h>
typedef void (*genfn_t)(void);
typedef int (*printf_t)(const char *, ...);
int call(genfn_t arg)
{
printf_t fn = (printf_t)arg;
fn("Hello world!\n");
}
int main()
{
call((genfn_t)printf);

i'm off to bed now i don't give a shit about arguing about this inane bullshit topic, it should be completely obvious why you wouldn't use a database as some sort of state machine, your program is the state machine and you write the "produce" to the database, not every single variable etc of the program, fuck you

>tfw stray newlines in input stream fuck everything
Basically I have to read line by line. Line is either a character, number, or empty(newline).

twice as fast, so half as stupid i guess?
i'm going to make a computer algebra system.
How the fuck am i going to represent the data, and work on it internally.
So far i have these two representations, i came up with both but i have no idea of the advantages and disadvantages of each
Type A:class Node {
int type, id;
vector<Node*> children;
}
class Leaf
{}
class Tree{
Node* main;
vector<Leaf*> Constants;
}
No inheritance for Node, if its a connection Node, it will hold a type and ID that both show what kind of node it is.
i.e. a + could be a Type 1 ID 1
a * Type 1 ID 2
a cos Type 2 ID 1
a sin Type 2 ID 2
and so on based on what i tell each type is.
as for leaf nodes, they have 0 children and they have a type that tells what kind of leaf node it is. The ID is used as an index to where the data it holds in the Leaf vector.
Leaf class is basically a father class that is used as a base
ie. class Variable : public Leaf
or class Number : public Leaf
or class Franction : public Leaf
Type B:class Node{
}
class Connection:public Node;
class Leaf: public Node;
Where everything inherits from Node.
and i'd use virtual functions to represent how each should react to a certain thing that happens.
feels like the least memory hungry implementation but the most headache inducing with having to try and handle covering the tree and stuff.
It kinda annoys me that i can't find a decent thing that shows how each and every implementation is good and bad out there.
and i saw yacas, but for some reason, i can barely understand anything in the code.

For starters, why aren't you using a for loop? There is absolutely no reason for that to be a while loop.
There is absolutely no reason to check any even numbers (besides 2) because they are all guaranteed to not be prime.
You only need to check up to the square root of num, as no factors of it are going to be larger than that.
>>54264830
>For starters, why aren't you using a for loop? There is absolutely no reason for that to be a while loop.

when working with overloaded operators, how do you properly resolve the scope (namespace? what's the term?) of the operators?
eg:cout << a == b << endl;
where the bitshift operator is the standard overloaded output operator and the equality operator is overloaded to compare objects 'a' and 'b' and return a bool. compiler spits an endless amount of warnings out at me, so i'm pretty sure i'm missing a step.

How to get a random word from a file that has one word per line?
My first idea was to get the file size with fseek + ftell, then when I want to get a random word, fseek to a position less than the file size, then read chars until a newline, then fgets. However, I read that the method of getting file size with fseek, ftell isn't portable with Windows, which is what my professor uses
Should I unironically call fgets a random number of times less than the number of lines in the file?

Technically you have a few extra bytes in there that aren't always used. But vtables in OOP are costly too. I'm just not a big fan of OOP, I'm currently writing an entire language parser and evaluator with type inference and I'm not using inheritance once, just not a big fan.
The pro to doing it this way is that it's really easy to obtain the children expressions of any node, for if you want to apply an operation to all sub expression (e.g., search for a variable by name). But it is a matter of style. The OOP way would bestruct Expr {
virtual ~Expr () = 0;
virtual std::vector<Expr*> get_children () {
return std::vector<Expr*>();
}
};
Expr::~Expr () {}
struct ExprVariable : public Expr {
std::string name;
// ...
};
struct ExprConstant : public Expr {
float constant;
// ...
};
It's more boilerplate than I'd be happy writing but if you want to OOP, then OOP away
>>54265250
You are right.
i*i <= n would probably be slighly faster, no?
>>54265284
sqrt is only executed once (any compiler would perform an operation this simple), while yours has a multiplication every loop. If you were super paranoid about that optimisation not happening, you could pull the sqrt out of the loop.
Yours MIGHT be slightly faster for small numbers, but would definitely be slower for big numbers.

i'm still learning, why would i say no to OOP alternatives
also didn;t know vtables were performance costly.
styles wont matter if i end up with a better result, plus learning more style might ease me up into reading code done by other people.

Are you fucking serious? Those are two completely different languages.
>>54262333
I am trying to work out how to make a name proper case and pAtErN case with C++. This is what I have so far. I have already figured out upper case and lower case.void toProper(char *p)
{
// write code to convert to proper case i.e. firts capital and rest small
if (*p == 0)
{
while (*p)
{
*p = (*p>='a' && *p<='z') ? *p=*p-32 : *p;
p++;
}
}
else
{
while (*p)
{
*p = (*p>='A' && *p<='Z') ? *p=*p+32 : *p;
p++;
}
}
}
void toPattern(char *p)
{
// write code to convert to the pattern ... aBcDeFgHiJ...one capital and one small
}
How do I do this? I thought I could just use an if statement for proper case, and then modular arithmetic for the pattern (even odd), but it doesn't work.
>>54265756
Oh my fucking god you autist. C++ has all the same features as C + OOP.
>>54265786
You clearly know nothing about either language.
>>54265786

wow
If we decided to write the project in one language, it would be completely different than if it were written in the other

standards compliant C doesn't even compile in a C++ compiler
>>54265775
God damn, that is some shit code.
Also, I don't know enough about the input the function expects to be able to help.
Is it supposed to be only a single word or a sentence?
If it's a sentence, is it supposed to output "hElLo WoRlD" or "hElLo wOrLd"?
You guys sure do like Java huh?

I'm sure less people would vote for java if c and c++ were separate. Many faggots here hate one or the other so wouldn't vote for both together, not to mention that grouping them like that is pants-on-head retarded.

What I meant was a C styled language and based on the framework we chose we'd go straight C or C++. I figured most people know those languages and would feel comfortable working in either one. So I grouped them together because of the library space and similarities.

c89. c99 is bloat
So I'm starting with C# and for my first little application I'm gonna build a time clock application. I want to be able to add employees, allow employees to clock in and out and record their times to a text file. What I'm curious about is how to structure it in an OO way. I've read you should typically convert nouns into objects so I imagine I should have an employee class and a time clock class.
I'm not sure how to split up the methods though. Should the employee class have a clock in method or should the time clock have it? Or should I only have a time clock or employee class that has all the functionality?
I guess my basic point is, how do I figure out how to structure my applications (simple as they may be)?
>>54266156
Go home, granddad.

You'll have multiple employees. They should each contain their in/out times
>>54266162
>how do I figure out how to structure my applications
trial and error. Or read up on shit like domain-driven design and CQRS, and then still figure it out by trial and error but possibly with fewer errors now.
C is eternal. Everything else is dust in the wind.
>>54266232
That is my intention, I currently have all the functionality set up in the time clock class and each employee has a folder with their employee ID and a text file for each date inside.
>>54266231
it's a language. It can't have an ideology. More than that - it's open source and free. If sjw maintainers bother you so much you could, for example: fork it, name it nigger-rust and still keep fetching from upstream and using the results of sjws' work without having being able to do anything about it short of changing the license.

Whiny wanker with the retarded CS professor here
(She told us 5 games, 3 of which we will have to make in C on the final exam)
I thought I'd be able to do all 5 today but I wasted a lot of time mucking around, spent the last two hours making hangman because I am apparently pants on head retarded. It's only 250 lines too. There's a 3/5 chance that I didn't waste that time though, so it's worth it.
