Rust Program: Calculate sum of range of numbers

Last update on December 21 2024 10:22:28 (UTC/GMT +8 hours)

Write a Rust program that iterates over a range of numbers and calculates the sum of all numbers.

Sample Solution:

Rust Code:

fn main() {
    // Define the start and end values for the range
    let start = 1;
    let end = 10;

    // Calculate the sum of numbers in the range using the sum() method
    let sum: i32 = (start..=end).sum();

    // Print the sum of numbers from start to end
    println!("Sum of numbers from {} to {} is: {}", start, end, sum);
} 

Output:

Sum of numbers from 1 to 10 is: 55

Explanation:

In the exercise above,

• Define the start and end values of the range (inclusive).
• Use the "sum()" method on the range to calculate the sum of all numbers within the range.
• Finally the result is printed to the console.
