Console application that draws a heart in C #
Prologue
This code is not optimized or idealized, it is very simple and will be understandable for beginners (who I am), so I hope to understand). Well, this application was also created for the fun of it.
Here’s what I got as a result:
The essence of the work
We have an array (screen), also called a screen buffer, which displays pixels (characters) on the screen in a specific order. In fact, we are making a program that draws graphs of functions (the heart is also just a graph of a function), the disadvantage of such an application will be that the graphs will be extremely inaccurate, because they contain only integers, but for displaying figures like a circle , the heart is quite suitable, the larger the scale – the more accurate it will be.
Creation
In the console itself, it is better to select the “Raster Fonts 8×8” font so that the character width = height, so as not to divide the height by two in the future.
Console.Title = "HABR @Frog_cry_too"; //TITTLE КОНСОЛИ
Console.ForegroundColor = ConsoleColor.Red; //ЦВЕТ ТЕКСТА В КОНСОЛЕ
//ИНИЦИАЛИЗИРУЕМ МАССИВ
int height = 100, width = 100;
char[,] buffer = new char[height, width];
//ЗАДАЕМ РАЗМЕРЫ КОНСОЛИ(РАЗМЕРЫ ТУТ ОПРЕДЕЛЯЮТСЯ ПО-СИМВОЛЬНО, ТОЕСТЬ 'СИМВОЛ' = 1)
Console.SetWindowSize(width, height);
Console.SetBufferSize(width, height);
//ЗАПОЛНЯЕМ МАССИВ
for(int i = 0; i < height; i++)
{
for(int j = 0; j < width; j++)
{
//ВЫВОДИМ ТОЧКУ В ЦЕНТР БУФФЕРА
int x = j - width / 2;
int y = -1 * (i - height / 2); //ПО-СКОЛЬКУ РЯДЫ МАССИВА БУДУТ ИНИЦИАЛИЗИРОВАТЬСЯ СВЕРХУ ВНИЗ (ОТ 0 ДО 100), НАМ НАДО ДОМНОЖИТЬ НА -1
//ЗАДАЕМ УСЛОВИЕ ОТБОРА(ПИШЕМ ФУНКЦИИ ПО КОТОРОЙ БУДЕТ РИСОВАТЬСЯ ГРАФИК)
//ПО-СКОЛЬКУ ФУНКЦИЯ БОЛЬШАЯ, Я ДЕЛЮ ЕЕ НА ДВЕ ЧАСТИ
int firstPart = x * x;
int secondPart = (int)((y - Math.Sqrt(Math.Abs(x))) * (y - Math.Abs(x)));
int heartSize = 500; //РАЗМЕР СЕРДЦА
if (firstPart + secondPart <= heartSize)
{
buffer[i, j] = '♥'; //ЗАПОЛНЯЕМ СЕРДЦЕ СИМВОЛОМ КОТОРЫМ ХОТИМ
}
else
{
buffer[i, j] = ' '; //ЗАПОЛНЯЕМ НЕ НУЖНУЮ НАМ ЧАСТЬ БУФФЕРА СИМВОЛОМ КОТОРЫМ ХОТИМ
}
}
}
//ВЫВОДИМ МАССИВ
for(int i = 0; i < height; i++)
{
for(int j = 0; j < width; j++)
{
Console.Write(buffer[i, j]);
}
Console.WriteLine();
}
//ЧТОБ НЕ ВЫВОДИЛСЯ ТЕКСТ ЗАВЕРШЕНИЯ ПРОГРАММЫ
Console.ReadLine();/*РЕЗУЛЬТАТ
ПРАВДА ТУТ ОН ВЫТЯНУТЫЙ, ИБО ШРИФТ ДРУГОЙ), ЧТОБ ОН СТАЛ МЕНЬШЕ ПО
ВЫСОТЕ, ДОСТАТОЧНО X ПОДЕЛИТЬ НА НУЖНЫЙ КООФИЦИЕНТ, НУ ЭТО ПОНЯТНО ИЗ ОСНОВНЫХ
ПОНЯТИЯХ ПО ФУНКЦИЯМ*/

♥EPILOGUE
In my code, I made methods for calling different charts – for easy use (well, I removed them into a separate class). Perhaps I will do the second part where I will show the code with separate methods and possible shading variations (well, I will show their principle).
