How to create a Vector of Numbers from 1 to N in Rust

How to create a Vector of Numbers from 1 to N in Rust ?

Answer

To create a vector of numbers from 1 to N in Rust, you can use a simple loop to generate the numbers and push them into a vector.


✐ Examples

1 Create Vector of Numbers from 1 to N

In this example,

  1. We define a function named generate_numbers that takes an argument n of type usize, which represents the end value.
  2. Inside the function, we create an empty vector named number_vector using the Vec::new() method.
  3. We use a for loop with an iterator i ranging from 1 to n (inclusive).
  4. Within the loop, we push each value of i into the number_vector vector using the push method.
  5. We return the number_vector vector containing the generated sequence of numbers.

Rust Program

fn generate_numbers(n: usize) -> Vec<usize> {
    let mut number_vector = Vec::new();
    for i in 1..=n {
        number_vector.push(i);
    }
    number_vector
}

fn main() {
    let n = 10;
    let numbers = generate_numbers(n);
    println!("Numbers from 1 to {}: {:?}", n, numbers);
}

Output

Numbers from 1 to 10: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

2 Create Vector of Numbers from 1 to 100

In this example,

  1. We define a function named generate_numbers that takes an argument n of type usize, which represents the end value.
  2. Inside the function, we create an empty vector named number_vector using the Vec::new() method.
  3. We use a for loop with an iterator i ranging from 1 to n (inclusive).
  4. Within the loop, we push each value of i into the number_vector vector using the push method.
  5. We return the number_vector vector containing the generated sequence of numbers.

Rust Program

fn generate_numbers(n: usize) -> Vec<usize> {
    let mut number_vector = Vec::new();
    for i in 1..=n {
        number_vector.push(i);
    }
    number_vector
}

fn main() {
    let n = 100;
    let numbers = generate_numbers(n);
    println!("Numbers from 1 to {}: {:?}", n, numbers);
}

Output

Numbers from 1 to 100: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100]
