## tuples
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
- Define a tuple structure to represent a student.
|
||
|
|
|
||
|
|
- Each student is identified by an id number of type i32, his/her name and his/her last name as a string Print the content of the tuple to stdout
|
||
|
|
|
||
|
|
- Then define three functions to return the id, first name and last name.
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```rust
|
||
|
|
pub fn id(student: &Student) -> i32 {
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn first_name(student: &Student) -> String {
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn last_name(student: &Student) -> String {
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a program to test you're functions
|
||
|
|
|
||
|
|
```rust
|
||
|
|
use tuples::*;
|
||
|
|
|
||
|
|
fn main() {
|
||
|
|
let student = Student(20, "Pedro".to_string(), "Domingos".to_string());
|
||
|
|
println!("Student: {:?}", student);
|
||
|
|
println!("Student first name: {}", first_name(&student));
|
||
|
|
println!("Student last name: {}", last_name(&student));
|
||
|
|
println!("Student Id: {}", id(&student));
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
|
Student: Student(20, "Pedro", "Domingos")
|
||
|
|
Student first name: Pedro
|
||
|
|
Student last name: Domingos
|
||
|
|
Student Id: 20
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
|
```
