Hello!
I have this code:
use std::io::stdin;
fn readln(s: &mut String) {
stdin().read_line(s).unwrap();
}
fn pow(n: i32, p: i32) -> i32 {
if p == 1 {
return n;
}
n * pow(n, p - 1)
}
fn main() {
let mut n = String::new();
let mut p = String::new();
println!("Enter the number:");
readln(&mut n);
println!("Enter the power:");
readln(&mut p);
let n = n.trim().parse().unwrap();
let p = p.trim().parse().unwrap();
let result = pow(n, p);
println!("You entered '{}^{}' and this equals '{}'", n, p, result);
}
My input is 5 and 2, next output:
Enter the number:
5
Enter the power:
2
You entered '5^2' and this equals '25'
But how do I get my input to be on the same line as the text? print! does not help (it is visible only after input)
My expected output:
Enter the number: 5
Enter the power: 2
You entered '5^2' and this equals '25'
Thanks for help!
