Rust Program: Implement Enum for Geometric shapes

Rust Structs and Enums: Exercise-4 with Solution

Write a Rust program that implements an enum Shape with variants representing different geometric shapes (e.g., Circle, Triangle, Square).

Sample Solution:

Rust Code:

// Derive the Debug trait for the Shape enum
#[derive(Debug)]
// Define an enum named 'Shape' with variants representing different geometric shapes
enum Shape {
    Circle,
    Triangle,
    Square,
}

fn main() {
    // Example usage: Create variables representing different shapes
    let circle = Shape::Circle;
    let triangle = Shape::Triangle;
    let square = Shape::Square;

    // Print the values of the variables representing shapes
    println!("Circle: {:?}", circle);
    println!("Triangle: {:?}", triangle);
    println!("Square: {:?}", square);
}

Output:

Circle: Circle
Triangle: Triangle
Square: Square

Explanation:

Here is a brief explanation of the above Rust code:

The code defines an enum named "Shape" with variants representing different geometric shapes: "Circle", "Triangle", and "Square". The "Debug" trait is automatically derived for the "Shape" enum, allowing debugging information.

• In the main() function,
• Variables 'circle', 'triangle', and 'square' are created, each representing one of the shapes defined in the "Shape" enum.
• The println! macro is used to print the values of these variables, allowing us to see which shape each variable represents.
