## strings |
||||
|
||||
### Instructions |
||||
|
||||
Write a function that receives a string slice and returns the number of character of the string |
||||
|
||||
### Expected Function |
||||
|
||||
```rust |
||||
fn char_length(s: &str) -> usize { |
||||
} |
||||
``` |
||||
|
||||
### Usage |
||||
|
||||
Here is a program to test your function. |
||||
|
||||
```rust |
||||
fn main() { |
||||
println!("length of {} = {}", "❤", char_length("❤")); |
||||
println!("length of {} = {}", "形声字", char_length("形聲字")); |
||||
println!("length of {} = {}", "change", char_length("change")); |
||||
println!("length of {} = {}", "😍", char_length("😍")); |
||||
} |
||||
``` |
||||
|
||||
And its output |
||||
|
||||
```console |
||||
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||
length of ❤ = 1 |
||||
length of 形声字 = 3 |
||||
length of change = 6 |
||||
length of 😍 = 1 |
||||
student@ubuntu:~/[[ROOT]]/test$ |
||||
``` |
