game_of_life | elegant implementation to John Conway

I am new to CMake and was experimenting with it. Here is folder structure: Structure of the project

I have CMakeLists.txt in every folder. The main CMakeLists.txt:

So I followed the Amethyst Pong tutorial and am now building a little Game of Life program. It works fine if I run it with cargo run but if I do cargo build and then run

I have an assignment to write a game of life in Java. Here are the rules for the game if you are unfamiliar with them: https://sv.wikipedia.org/wiki/Game_of_Life. I 'm following a guide with pseudocode that the teacher has given us. I'm at the last step where I have to write the actual algorithm that kills and spawns new life cells.

I feel like I've done everything right, but it's not working correctly and I don't know how I should proceed since I can't find any errors. I'm using a 2D Boolean array that I update once when I have calculated the new state of the board. The method for calculating neighbors and the other methods used is working correctly.

Hi im having problems with my c code it keeps crashing with no error and im not sure why. i am trying to find the value at a point inside a 2d array for example [1][1] and see what the value is there (only 1 or a 0) and then process the value depending on if its 1 or a 0 but the program keeps crashing with no error and im not sure why.please help

I am trying to write a game of life program in a console app but keeping the runtime exception that my instantiated cell object is null.

I am looping through a 2d array and creating the objects then I am visualizing them if they are alive. I keep getting an error when I try access the position

(Console.WriteLine(cell.Isalive.ToString());)

It always happens when I try access my objects properties even through they have values

I'm working on the following problem from Leetcode:

Given a board with m by n cells, each cell has an initial state live (1) or dead (0). Each cell interacts with its eight neighbors (horizontal, vertical, diagonal) using the following four rules (taken from the above Wikipedia article):

Any live cell with fewer than two live neighbors dies, as if caused by under-population. Any live cell with two or three live neighbors lives on to the next generation. Any live cell with more than three live neighbors dies, as if by over-population.. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction. Write a function to compute the next state (after one update) of the board given its current state.

Follow up: Could you solve it in-place? Remember that the board needs to be updated at the same time: You cannot update some cells first and then use their updated values to update other cells.

My solution is modeled after the solution offered by another user on the website, so adding their solution description.

In the beginning, every cell is either 00 or 01. Notice that 1st state is independent of 2nd state. Imagine all cells are instantly changing from the 1st to the 2nd state, at the same time. Let's count # of neighbors from 1st state and set 2nd state bit. Since every 2nd state is by default dead, no need to consider transition 01 -> 00. In the end, delete every cell's 1st state by doing >> 1. For each cell's 1st bit, check the 8 pixels around itself, and set the cell's 2nd bit.

Transition 01 -> 11: when board == 1 and lives >= 2 && lives <= 3. Transition 00 -> 10: when board == 0 and lives == 3.

My code is failing and I'm not sure why. Here's the output vs expected:
