Rust Program: Define Student Struct & Print details

Last update on June 07 2025 13:04:05 (UTC/GMT +8 hours)

Write a Rust program that defines a struct Student with fields like name, age, and email. The next step is to write a function that prints out the student's details.

Sample Solution:

Rust Code:

// Define a struct named 'Student' with fields: name, age, and email
struct Student {
    name: String,
    age: u32,
    email: String,
}

// Define a function to print the student's details
fn print_student_details(student: &Student) {
    println!("Name: {}", student.name);
    println!("Age: {}", student.age);
    println!("Email: {}", student.email);
}

fn main() {
    // Create a student instance
    let student = Student {
        name: String::from("Bonolo Itxaro"),
        age: 20,
        email: String::from("[email protected]"),
    };

    // Print the student's details using the function
    print_student_details(&student);
}

Output:

Name: Bonolo Itxaro
Age: 20
Email: [email protected]

Explanation:

Here is a brief explanation of the above Rust code:

struct Student { ... }: Defines a struct named "Student" with fields 'name', 'age', and 'email'. Each field has its respective data type.
fn print_student_details(student: &Student) { ... }: Defines a function named "print_student_details()" that takes a reference to a "Student" instance as a parameter. Inside the function, it prints out the student's details using println! macro.
fn main() { ... }: This is the entry point of the program.

Inside main():

A "Student" instance named 'student' is created with sample details.
The "print_student_details()" function is called with a reference to the 'student' instance to print out its details.
