rustHow to loop N times in Rust
Looping in Rust is done using the loop
keyword. The following example shows how to loop N
times:
let mut n = 0;
loop {
println!("Looping {} times", n);
n += 1;
if n >= N {
break;
}
}
This code will print Looping 0 times
, Looping 1 times
, ..., Looping N-1 times
.
The code consists of the following parts:
let mut n = 0;
: This declares a mutable variablen
and initializes it to0
.loop {
: This starts the loop.println!("Looping {} times", n);
: This prints the current loop count.n += 1;
: This increments the loop count.if n >= N {
: This checks if the loop count is greater than or equal toN
.break;
: This exits the loop if the condition is true.}
: This closes the loop.
