Rust program to read coordinate points and determine its quadrant

Given coordinate points (x, y), we have to determine its quadrant using the Rust program.
Last Updated : October 01, 2021

Problem Statement

Here, we will read the coordinate points from the user. Then we will determine the quadrant and print the result.

Quadrant:

There are four Quadrants based on the origin (Meeting point of the two axes).

In the first quadrant, both x and y have positive values.
In the second quadrant, x is negative and y is positive.
In the third quadrant, x and y are negative
In the fourth quadrant, x is positive and y is negative.

Consider the following graph,

Program/Source Code

The source code to read coordinate points and determine their quadrant is given below. The given program is compiled and executed successfully.

// Rust program to read coordinate points 
// and determine its quadrant

use std::io;

fn main() 
{
    let mut X:i32   =0;
    let mut Y:i32   =0;
    let mut res:i32 =0;
   
    let mut input1 = String::new();
    let mut input2 = String::new();
    
    println!("Enter value of X: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    X = input1.trim().parse().expect("Not a valid number");
    
    println!("Enter value of Y: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    Y = input2.trim().parse().expect("Not a valid number");
    
    if X == 0 && Y == 0
    {
        println!("Point ({0}, {1}) lies at the origin", X, Y);
    }
    else if X > 0 && Y > 0
    {
        println!("Point ({0}, {1}) lies in the First quadrant", X, Y);
    }
    else if X < 0 && Y > 0
    {
        println!("Point ({0}, {1}) lies in the Second quadrant", X, Y);
    }
    else if X < 0 && Y < 0
    {
        println!("Point ({0}, {1}) lies in the Third quadrant", X, Y);
    }
    else if X > 0 && Y < 0
    {
        println!("Point ({0}, {1}) lies in the Fourth quadrant", X, Y);
    }
}

Output

RUN 1:
Enter value of X: 
12
Enter value of Y: 
15
Point (12, 15) lies in the First quadrant

RUN 2:
Enter value of X: 
-5
Enter value of Y: 
-10
Point (-5, -10) lies in the Third quadrant
