RUST While Loop

A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement. The while loop executes the instructions each time the condition specified evaluates to true

Example of RUST While Loop


fn main(){
 let mut x = 0;
 while x < 10{
 x+=1;
 println!("inside loop x value is {}",x);
 }
 println!("outside loop x value is {}",x);
}

Output for above code:


inside loop x value is 1
inside loop x value is 2
inside loop x value is 3
inside loop x value is 4
inside loop x value is 5
inside loop x value is 6
inside loop x value is 7
inside loop x value is 8
inside loop x value is 9
inside loop x value is 10
outside loop x value is 10
