Rust program to demonstrate the use of abs() function

Given a number, we have to find its absolute value using the abs() function.
Last Updated : September 28, 2021

Problem Statement

Here, we will read the number from the user. Then we will find the absolute value of the number and print the result.

Program/Source Code

The source code to demonstrate the use of abs() function is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate the 
// use of abs() function

fn main() {
    let mut n1:i32 = -5;
    let mut n2:i32 = 7;
    let mut res:i32 = 0;
    
    res = n1.abs();
    println!("Absolute value is n1: {}",res);
    
    res = n2.abs();
    println!("Absolute value is n2: {}",res);
}

Output

Absolute value is n1: 5
Absolute value is n2: 7

Explanation

Here, we created two integer variables n1 and n2. Then we found the absolute value of n1 and n2 using the abs() function. After that, we printed the result.
