Rust Program: Calculate product of Tuple elements

Last update on December 21 2024 10:22:29 (UTC/GMT +8 hours)

Write a Rust program that iterates over a vector of tuples (i32, i32) and calculates the product of the first and second elements of each tuple.

Sample Solution:

Rust Code:

fn main() {
    // Define a vector of tuples
    let tuples = vec![(10, 20), (30, 40), (50, 60)];

    // Iterate over each tuple in the vector
    for &(x, y) in tuples.iter() {
        // Calculate the product of the first and second elements of the tuple
        let product = x * y;
        // Print the product
        println!("Product of ({}, {}) is {}", x, y, product);
    }
}

Output:

Product of (10, 20) is 200
Product of (30, 40) is 1200
Product of (50, 60) is 3000

Explanation:

In the exercise above,

• Define a vector 'tuples' containing a list of tuples (i32, i32).
• We use a "for" loop with tuple pattern matching to iterate over each tuple in the vector.
• For each tuple (x, y), we calculate the product x * y and print it along with the original tuple elements.
