    loop { // infinite loop
        count += 1;
 
        if count == 4 {
            println!("count == 4");
            continue;
        }
 
        println!("{}", count);
 
        if count == 7 {
            println!("count == 7 -> break");
            break;

fn main() {
    let mut i = 0;
    let mut count = 0u16;
 
    // Infinite loop with a condition that never changes
    while i >= 0 {
        println!("i = {}", i);
        i += 1;
        
        count += 1;
 
        if count == 4 {
            println!("count == 4");
            continue;
        }
 
        println!("{}", count);
 
        if count == 7 {
            println!("count == 7 -> break");
            break;
        }
    }
}
