Odległość punktu od prostej

Opis problemu

Implementacja bez struktury

#include <iostream>
#include <cmath>

using namespace std;

double pointLineDistance(double line1X, double line1Y, double line2X, double line2Y, double pointX, double pointY) {
    double xDiff = line2X - line1X;
    double yDiff = line2Y - line1Y;

    double result = abs(yDiff * (line1X - pointX) + xDiff * (pointY - line1Y)) / sqrt(yDiff * yDiff + xDiff * xDiff);

    return result;
}

int main() {
    double line1X = -3;
    double line1Y = -4;
    double line2X = 7;
    double line2Y = 6;
    double pointX = -5;
    double pointY = -8;

    double distance = pointLineDistance(line1X, line1Y, line2X, line2Y, pointX, pointY);

    cout << distance << endl;
