rustHow do I reuse a variable in Rust?

Reusing a variable in Rust is easy and straightforward. You can simply assign a new value to the same variable. For example:

let mut x = 5;
x = 10;

This will assign the value 10 to the variable x.

You can also use the same variable in a loop, for example:

let mut x = 0;
for i in 0..10 {
    x += i;
}
println!("x = {}", x);

This will print out the value 45.

The parts of the code are:

• let mut x = 0;: This declares a mutable variable x and assigns it the value 0.
• for i in 0..10 {: This starts a loop that will iterate 10 times.
• x += i;: This adds the value of i to x each time the loop iterates.
• println!("x = {}", x);: This prints out the value of x.
