Programming exerises

Software has three parts:
1. Data
2. Algorithms
3. DOCUMENTATION

what a retarded assignment, it basically forces you to write bad practice C++
a) why the hell would you use a 2d array to represent that? a 1d array/vector of structs is the obvious choice
b) forces you to hard code a predefined array, completely pointless
c) with a vector of structs the appropriate way is to write a sort algorithm or use std::sort (in real life) with an operator overload for

breaking it down to smaller problems and decisions:

a) deciding on data structure for the gradebook
Assignment really puts it terribly as it explicitly tells you to use 2-dimensional array. In statically typed language where each column as different type, this is weird way to put it. I would suggest to make a struct (or class) Row (or Student or whatever you want to name it) with each column as member field - the whole gradebook is then just a 1-dimensional array of rows.

b) write a function that generates new Row and returns it
subproblems here: random integer from [0,100], pick a random name from array of names (can also be pick number number frm [0,len(names)) ), merge 2 strings into one. Construct the Row with them and return it. I'm confused here about the sequential number. It could be one of following: index in array or incrementing ID of student. I would guess it should be the latter - either hold a global state or take the Seq.number as the only input.

c) Sorting array by specific key
Now I don't know if you can use a sort function from standard library, but providing custom comparison function is a common thing (it should return a.oc > b.oc).

d) printing rows with special rules
You should not modify the rows in any way to accomplish this, no changing of OC fields is happening. Write some display function that takes a row and reports it to (probably standard output) following given rules. Since the gradebook is now sorted, this should be performed as simple for-each loop and calling the display function on each entry.

e) calculating average and finding sudent closest to average
I didn't quite get the ", who passed the exam". Do this in 2 passes - first calculate the average, second find the closest person. It's the same as searching max or min in array, except you are searching min of abs(oc - average)

that's how a sane person would solve it, but OPs teacher could subtract points for not following instructions

Guys main question is how or which site provides step by step learning so I teach myself to learn this, don't do my homework.

Or am I supposed to just, learn as much as I can until it clicks.

part of the process is to learn as much as you can until it clicks, it takes time to process and after a certain amount of hours you adapt

you could try something like codewars, solve a kata every day

i would also recommend starting your own little project on the side with something you're motivated to work on (it's impossible to enjoy the kind of exercise you showed)

don't expect that your teacher will teach you the right way to do things, he might well teach you to become a bad programmer, find out yourself

I'm not saying all of them are good or worth doing, but I hope it helps you in some way

ty, I have two side projets, one GUI in python and other GUI in C++ and I'm doing fine and understand how code works, even though I copy a lot, but I still learn new things every day and at least I can write a GUI that has buttons and those buttons functions, etc.. something useful.

However, then we get assignments like I showed and I just fucking freeze, because I don't even know where to start.

this is not to help you with the homework, but to show you how this would typically be solved in C++ in a real application
all it does is generate a data structure and sort according to oc, the rest of the items can easily be solved from this base

#include
#include
#include
#include

struct entry
{
std::string name;
int kv, rv, vi, oc;
};

int
gen_random()
{
return rand() % 101;
}

int
main(void)
{
const int n_students = 166;
std::vector gradebook;

for(int i = 0; i < n_students; ++i)
gradebook.push_back(entry{"name" + std::to_string(gen_random()),
gen_random(),
gen_random(),
gen_random(),
gen_random()});
std::sort(
gradebook.begin(),
gradebook.end(),
[](const entry& lhs, const entry& rhs) { return lhs.oc > rhs.oc; });

for(auto e : gradebook)
std::cout

I get it, I just didn't know what to point out that was missing in my learning.

I guess it's time to wake up earlier and work harder and longer hours. It's just insane workload and if I'm not doing assignments and going to lectures, I'm learning. The fucked up part is that assignments take up few days to do usually and you can't plagiarize or you end up being kicked out of school.

So yeah, it's like I'm getting a bonus when I have a time to study math for example, since other time is spent on fucking assignments. Idk what to think of it, I asked myself few times already if it is that I'm not studying enough or if this first two semesters are really set up to be a filter and only the best get through. It's like there's no days off, if you actually want to make something out of it. I feel like I was working less hard and less stressfull when I had a full time physical job that I did 6x per week for 8 hours per day than now that I'm in college and have 24hours per day free to do anything.

Not sure what to think of it. I like the filter appeal, but too much is too much sometimes and you end up sacrificing spending time on some retarded assignments and then lack the study time for things that matter, like programming and math, despite already working all day everyday for 7 days per week.

I don't know how Jow Forums or /sci/ thinks CS degree is meme, it's the opposite in my case.

They think it's a meme because they don't have CS jobs.
