Rust Function: Safe Division with Error handling

Last update on December 21 2024 10:22:07 (UTC/GMT +8 hours)

Write a Rust function that divides two numbers and prints the result or an error message if division by zero occurs.

Sample Solution:

Rust Code:

fn divide(x: f64, y: f64) {
    if y == 0.0 {
        println!("Error: Division by zero!");
    } else {
        let result = x / y;
        println!("Result: {}", result);
    }
}

fn main() {
    let numerator = 10.0;
    let denominator = 0.0;
    divide(numerator, denominator);
}

Output:

Error: Division by zero!

Explanation:

Here's a brief explanation of the above Rust code:

• The "divide()" function takes two f64 parameters, 'x' (numerator) and 'y' (denominator).
• It checks if the denominator is zero. If it is, it prints an error message.
• If the denominator is not zero, it performs the division and prints the result.
• In the "main()" function, we demonstrate calling the "divide()" function with a numerator of 10.0 and a denominator of 0.0, resulting in a division by zero error.
