Practice - 012

A program to explain short hand arithmetic operators

fn main() {
    practice12()
}

fn practice12() {
    let mut a = 3;

    println!("a is {}", a);

    a += 1;
    println!("After a += 1, \t a is {}", a);

    a -= 1;
    println!("After a -= 1, \t a is {}", a);

    a *= 2;
    println!("After a *= 2, \t a is {}", a);

    a /= 3;
    println!("After a /= 3, \t a is {}", a);
}

Result

a is 3
After a += 1,    a is 4
After a -= 1,    a is 3
After a *= 2,    a is 6
After a /= 3,    a is 2
