Program to Determine Quadrants of a Given Coordinate in C++ and Java

Quadrants of a Coordinate

A coordinate plane is divided into four quadrants:

• Quadrant 1: (+x, +y)
• Quadrant 2: (-x, +y)
• Quadrant 3: (-x, -y)
• Quadrant 4: (+x, -y)

We will explore three methods to determine the quadrant of a given coordinate using C++ and Java programming.

C++ Implementation

The following are three different methods to determine the quadrant of a coordinate in C++.

Method 1: Using If-Else Statements

#include 
using namespace std;

void findQuadrant(int x, int y) {
    if (x > 0 && y > 0)
        cout << "Quadrant 1" << endl;
    else if (x < 0 && y > 0)
        cout << "Quadrant 2" << endl;
    else if (x < 0 && y < 0)
        cout << "Quadrant 3" << endl;
    else if (x > 0 && y < 0)
        cout << "Quadrant 4" << endl;
    else
        cout << "Point lies on the axis" << endl;
}

int main() {
    int x, y;
    cout << "Enter x and y coordinates: ";
    cin >> x >> y;
    findQuadrant(x, y);
    return 0;
}

Java Implementation

The following are three different methods to determine the quadrant of a coordinate in Java.

Method 1: Using If-Else Statements

import java.util.Scanner;

public class QuadrantFinder {
    public static void findQuadrant(int x, int y) {
        if (x > 0 && y > 0)
            System.out.println("Quadrant 1");
        else if (x < 0 && y > 0)
            System.out.println("Quadrant 2");
        else if (x < 0 && y < 0)
            System.out.println("Quadrant 3");
        else if (x > 0 && y < 0)
            System.out.println("Quadrant 4");
        else
            System.out.println("Point lies on the axis");
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter coordinates (x, y): ");
        int x = scanner.nextInt();
        int y = scanner.nextInt();
        findQuadrant(x, y);
        scanner.close();
    }
}
