Simple C++ Bean machine program @KTSI

This is a simple Bean machine program done in C++ for KTSI.

This is how it works, you drop 100 balls and they fall in 6 different boxes.

Bean MachineAnd this is how the C++ output should look like:

Bean Machine outputAnd here is how its done:

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main (int argc, char * const argv[]) {

	// initial
	int ballCount = 100;
	int box[6] = { 0, 0, 0, 0, 0 };
	string line = " +-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-->";
	string numbers = " 0     5     10     15     20     25     30     35     40     45     50";
	int leftorright = 0;

	// Need for Random Numbers
	srand ( time(NULL) );

	// Rund ballCount (100) zahl = rand() % 2;
	for (int i=0; i<ballCount; i++) {
			int counter = 0;

		for (int j=0; j<5; j++) {
			// left or right
			leftorright = rand() % 2;
			counter = counter + leftorright;
		}
		box[counter] = box[counter]++;

	}	

	// Output
	cout << numbers << endl << line << endl;
	for (int t=0; t<6; t++) {
		cout << t << " |";
		for (int u=0; u < box[t]; u++) {
			cout << "#";
		}
		cout << " " << box[t] << endl << line << endl;
	}
	return 0;
}

I also did this program in Powershell

Simple C++ rect2polar program @KTSI

This is another simple C++ program done for KTSI. This one converts rectangular to polar coordinates.

#include <iostream>
#include <cmath>

using namespace std;

void rect2polar(double &value, double &angle, double x, double y) {
    value = sqrt(pow(x, 2) + pow(y, 2));
    angle = 180 / M_PI * atan2(y,x);
}

int main(){
    double value;
    double angle;
    double x = 4;
    double y = 3;

    rect2polar(value, angle, x, y);

    cout << "x = " << x << endl;
    cout << "y = " << y << endl;
    cout << "value = " << value << endl;
    cout << "angle = " << angle << endl;
    //system("PAUSE");
    return 0;
}

Simple C++ lottery program @KTSI

Here is a simple C++ lottery program done for the KTSI.

#include <iostream>
#include <cstdlib>

using namespace std;

int main (int argc, char * const argv[]) {

	int numberCount;
	int maxNumbers;

	cout << "Lottery Game" << endl << "=================================" << endl;
	cout << "How many Lottery Numbers = ";
	cin >> numberCount;
	cout << "from 1 to ? ";
	cin >> maxNumbers;
	cout << "You have chosen " << numberCount << " Lottery Numbers from 1 to " << maxNumbers << endl;

	int lotteryNumbers[numberCount];
	int i, j;
	bool newNumber;

	srand(0);
	for(i=0; i<numberCount; i++) // get numbers
	{
		do
		{   // Check Random
			lotteryNumbers[i] = rand() % maxNumbers + 1;
			newNumber = true;
			for (j=0; j<i; j++)
			{
				if (lotteryNumbers[j]==lotteryNumbers[i])
				{ // Check for existing numbers
					newNumber = false;
				}
			}
		} while (!newNumber);
	}
	for (i=0; i<numberCount; i++)
	{
		cout << lotteryNumbers[i] << " ";
	}
	cout << endl;
}
