Flow Control in Rust

Rust provides several options for flow control, including if statements, while loops, and more. Here are some simple examples for each:

if Statements

The if statement allows you to execute code based on a condition.

#![allow(unused)]
fn main() {
let number = 5;

if number < 10 {
    println!("The number is less than 10");
} else {
    println!("The number is 10 or greater");
}
}

while Loops

The while loop allows you to execute code repeatedly as long as a condition is true.

#![allow(unused)]
fn main() {
let mut count = 0;

while count < 5 {
    println!("Count is: {}", count);
    count += 1;
}
}

for Loops

The for loop allows you to iterate over a range or collection.

#![allow(unused)]
fn main() {
for number in 1..5 {
    println!("The number is: {}", number);
}
}

match Statements

The match statement allows you to compare a value against a series of patterns and execute code based on which pattern matches.

#![allow(unused)]
fn main() {
let number = 3;

match number {
    1 => println!("One"),
    2 => println!("Two"),
    3 => println!("Three"),
    _ => println!("Something else"),
}
}

These are some of the basic flow control options available in Rust. Each of these constructs helps you manage the flow of your program effectively.
