I wrote a little program in Rust that just doesn't work.
use std::io;
fn main() {
println!("Enter a string: ");
let mut input = String::new();
io::stdin().read_line(&mut input).unwrap();
println!("you have entered:\n{}", input);
println!("enter a char which you wish to replace: ");
let mut char_to_be_replaced = String::new();
io::stdin().read_line(&mut char_to_be_replaced).unwrap();
println!("you have entered: {}", char_to_be_replaced);
println!("enter a replacement char:");
let mut replacement_char = String::new();
io::stdin().read_line(&mut replacement_char).unwrap();
println!("replacement char is: {}", replacement_char);
let result = input.replace(&char_to_be_replaced, &replacement_char);
println!("end result is: ");
println!("{}", result);
}
input is "asd, asd"
char_to_be_replaced is ","
replacement_char is "."
to my horror result is "asd, asd" instead of "asd. asd"
