分形学之Mandelbrot图形

用c++实现，输出在控制台

#include<iostream>
using namespace std;
int main() {
	double realCoord, imagCoord, realTemp, imagTemp, realTemp2, arg;
	int interation;
	char outPut[4]{ '.','o','O','@' };
	for (imagCoord = 1.2; imagCoord >= -1.2; imagCoord -= 0.05) 
	{
		for (realCoord = -0.6; realCoord <= 1.77; realCoord += 0.03) 
		{
			interation = 0;
			realTemp = realCoord;
			imagTemp = imagCoord;
			arg = realCoord * realCoord + imagCoord * imagCoord;
			while (arg < 4 && interation < 40)
			{
			realTemp2 = realTemp * realTemp - imagTemp * imagTemp - realCoord;
			imagTemp = 2 * realTemp * imagTemp - imagCoord;
			realTemp = realTemp2;
			arg = realTemp * realTemp + imagTemp * imagTemp;
			interation++;
			}
			std::cout << outPut[interation % 4];
		}
		cout << endl;
	}
	system("pause");
	return 0;
