In this program you have to solve 20 exercises. The time you need will be measured. If you break a record, you'll get an entry in the highscore list.
The program can be downloaded here.
You can only start it via command line, not by double-click.
If I can improve my code to make it more readable, please tell me how.

Below is my implementation of a generic linked list in swift. Unfortunately, Swift playgrounds won't run until the compiler is totally happy - often, that involves clang making me explicitly unwrap some optionals. I just want a general idea of how to restructure my code to avoid unwrapping optionals and to make more us... | stackexchange/codereview |
I have programmed Tic Tac Toe in C. How can I improve the code? I have been told that system("cls") is not secure, but I don't know any other way of clearing the screen.

I am working on this assignment to draw the flag of Liberia for my essentials of computer programming class.
I finished it but had extra time to kill and noticed that a couple similar blocks of code are not very concise and could be shortened with a loop, but right now I can't seem to form the code just right!

I recently wrote this up and am wondering if there is a better way to achieve the results I want.
Essentially, we're taking a given year and adding 'th, nd, rd, st' depending on the digit.
Any suggestions on how to shorten this code and make it better?

Lvl 1 upgradeable attributes
From before:
I've built the groundwork for an attributes (as in Strength,
Intelligence, not as in DebuggerHidden, TestMethod) framework for my
game. Each attribute can be upgraded and downgraded individually as

I'm a freshman in Python world, I used to program in C.
I wrote a function/method that returns the power of a number:
def pow(x, y):
powered = x
if y == 0:
return 1
while y > 1:
powered *= x
y -= 1
return powered
Mine is a logic question (correctly): if I set y = 0 then it ... | stackexchange/codereview |
My code sample for finding the mean for the case of pairs is:

p_avg =zeros(psize,float)
for i in range(0,Data.size):
for j in range(0,Data.size):

This is the crux of a problem found on one of those code challenge sites.
I'm fairly new to programming and this was a difficult challenge. I've attempted to solve this with stacks and calculating totals on the fly. I think this is pretty close to O(n). With the exception of values repeated without a larger value betwe... | stackexchange/codereview |
I am designing a planetary system simulator. The coordinates used are standard for JPanel (0,0 in the upper left corner).
My model is based on a class Body:

I am a Python beginner and wrote a script which should run on a Raspberry PI as a UDP server. It reads and writes to a serial device and has to process and forward JSON strings.
Because there is relatively much functionality included and I don't like cross compiling, I was too lazy to write a C program but instead chos... | stackexchange/codereview |
I have an application developed in ASP.NET Core C#, where according to a configuration it must replace certain urls of a text when an http request is made and the text must be returned as soon as possible in response, the text can change on each request.

I am trying to write a script to read a CSV file containing 1 million domain names, look up these domain names and store the results in another CSV file.
