Solution Review: Calculate (a + b)^3

Explore how to compute (a + b) to the third power in Rust by applying arithmetic operators and the pow function. Learn to declare variables and perform operations step-by-step, preparing you to use conditions in upcoming lessons.

We'll cover the following...

Solution :

Rust 1.40.0
fn test() {
    let a = 2;
    let b = 2;
    let c = i32::pow(a,3) + i32::pow(b, 3) + ( 3 * a * b * (a + b)) ; 
    println!("{}",c);  
}

Explanation

  • On line 2, a variable a with value 2 is declared.
  • On line 3, a variable b with value 2 is declared.
  • On line 4, addition takes place of :
    • a3a^3
