Rust Vector Initialization Guide

Last update on December 21 2024 10:19:30 (UTC/GMT +8 hours)

Write a Rust program to create an empty vector and add integers 1 to 10 to it. Print the vector.

Sample Solution:

Rust Code:

// Define the main function
fn main() {
    // Create an empty vector to store integers
    let mut numbers = Vec::new();

    // Use a for loop to add integers 1 to 10 to the vector
    for i in 1..=10 {
        numbers.push(i); // Add the current value of i to the vector
    }

    // Print the vector
    println!("The vector is: {:?}", numbers);
}

Output:

The vector is: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Explanation:

The above program uses a "for" loop to iterate over integers from 1 to 10 (inclusive) and adds each integer to the vector using the "push" method. Finally, it prints the vector using the "println" macro with the {:?} format specifier to display the contents of the vector.
