I am creating a planner/scheduling app using objects. I am just a beginner with object oriented programming, so any tips on how to better structure my classes would be very helpful.
Program Basics
The program consists of "objectives" and "checkpoints." An objective is essentially a goal, and che...
A code that determines the roots of a quadratic equation.
Also, determine the following based on the discriminant b2 – 4ac
If b2 − 4ac is positive, display: “There are TWO REAL SOLUTIONS.”
If b2 − 4ac is zero, display: “There is ONLY ONE REAL SOLUTION.”
If b2 − 4ac is negative, display: “There a...
I'm currently doing old exams from my course to train for my upcoming exam. What I'm wondering is about a code block which I will specify after I've presented the different files with code.
//upggift1.cc aka the main
#include "date.h"
#include <iostream>
using namespace std;
int main()

In the context of a library to generate random credit card, it would be nice to let the user the possibility to set some optional options on some cards. Lets take Visa. Two lengths are availables: 13 or 16 digits.
In C# a common implementation would be:
enum VisaLengthOptions
{
Thirteen,

So I wanted to start learning Rust and after 8th chapter of book I wanted to start to implement stuff so I thought of building password generator. I thought using crates will be not cool so I coded every aspect of this on my own.
Feel free to roast the code to the hell this will help me.

This is a simple arithmetic calculator, which parses mathematical expressions specified in infix notation using the shunting-yard algorithm. This is one of my personal projects and I would love to get expert advice.
After compiling, you can run the program with one command-line argument:

I made a 3D object in OpenGL. But I think my code is extremely bad and now, I want to make my code better.
Here is my code:
#include <GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_POLYGON);
glVertex2f(0.0, 0.0);
glVertex2f(0.5, 0.0);
glVertex2f(0.5, 0.5...
void heapify(int arr[], int n, int i)

int largest = i;
int l = 2*i + 1; // левый = 2*i + 1
int r = 2*i + 2; // правый = 2*i + 2
if (l < n && arr[l] > arr[largest])
largest = l;
if (r < n && arr[r] > arr[largest])
largest = r;
if (largest != i)

So I had used a while True: and implemented break, because I didn't figure out a cleaner solution that infinite loop. Is that a bad practice?
while True:
z = int(input("Y: "))
if (z >= 0 and z <= 20):
break
for x in range(z):
print("-" * (z-x) + "*" * x + " " * x + "-" * (z...
I'm looking for a more elegant or more efficient way to transcode a IEnumerable<uint> (~ array of 32bits int), which is a compact way to represent a byte[4] array, into a string as array of 8bits char:
public static string UintArraytoString(this IEnumerable<uint> x) =>
string.Concat(x.Select(o =
