LESSON 12 OF 348 · VARIABLES

Variable Reassignment in Rust in Rust

Lesson

You can always change the value stored in a variable with the assignment operator(=):

// Initializing with 5:
let mut my_var = 5;

// Assigning the value 10:
my_var = 10;

println!("{}", my_var); // Output: 10

First, this code creates a variable named my_var and initializes it with 5.

Then, the code assigns 10 to my_var. Now, when my_var appears again in the code, the program will treat it as if it is 10.

Assigning the Value of One Variable to Another:

You can also assign the value of some variable to another variable using the assignment operator:

let mut my_var = 5;
let my_num = 10;

my_var = my_num;

println!("{}", my_var); // Output: 10

First, this code creates a variable named my_var and initializes it with 5 and another variable named my_num and initializes it with 10.

Then, the contents of my_num (which is 10) is assigned to the variable my_var. Now, my_var also has the value of 10.

Assignment
Follow the Coding Tutorial and let's reassign some variables.
