Declaring Variables

In programming, variables are like containers that hold information. In Rust, a language known for being safe and reliable, how we declare and use variables is crucial for building strong software. To start, we use the word let to create a variable and give it a value. For example: let x = 10; Then, we can show the value of our variable using println!("X is {}", x); . But here's the catch: Rust doesn't like it when we try to change a variable after we've set it up. It wants us to keep things stable by default. So if we try to change x after setting it, Rust will throw an error. let x = 10; x = 20; // This won't work! But don't worry! Rust gives us a way to allow changes. We just need to use the keyword mut when we create the variable: let mut x = 10; x = 20; // Now it works! Now, let's talk about naming. In Rust, we should choose names that describe what our variables hold. It helps us and others understand the code better. Variable names ...
