in c/c++ we can iteration thought alphabets using ```
for(char alphabet = 'a'; alphabet <='z'; alphabet++ )
how can we apply this in rust using for loop

let a = "abcdefghijklmnopqrstuvwxyz".to_string;
for i in a.chars(){
print!(" {}",i);
}
i try one method
any other way to achieve this
fn main() {
for i in 97u8..=122 {
print!("{} ", i as char)
}
println!();
// LOL
println!("{}", (b'a'..=b'z').fold(String::new(), |acc, c| format!("{} {}", acc, c as char)));
// LOL
println!("{}", (97..=122).map(|i| (i as char).to_string()).collect::<Vec<_>>().join(" "));
// LOL
println!("{}", (0u8..26).fold(String::new(), |mut acc, i| { acc.push((i + 97) as char); acc }));
}

In Rust 'a'
is a UTF-8 character, in this case you probably want to iterate along ASCII characters, something like:
fn main() {
for c in b'a'..=b'z' {
println!("{}", c as char);
}
}
Which is similar to what @AurevoirXavier replied, just using the b
yte representation of the characters instead of their numeric value.
