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.
