Rust Program: Define character variable with first initial

Last update on December 21 2024 10:18:55 (UTC/GMT +8 hours)

Write a Rust program that defines a character variable and assigns it the first letter of your first name.

Sample Solution:

Rust Code:

fn main() {
    // Declare a character variable named 'temp' and assign it the first letter of your first name
    let temp: char = 'A';

    // Print the value of the 'first_initial' variable
    println!("First initial: {}", temp);
}

Output:

First initial: A

Explanation:

Here is a brief explanation of the above Rust code:

• 'fn main() { ... }': This is the program's entry point.
• 'let first_initial: char = 'A';': This line declares a character variable named 'temp' and assigns it the value ''A'', which represents the first letter of your first name. The 'char' type annotation specifies that 'temp' is a character variable.
• 'println!("First initial: {}", temp);': This line prints the value of the 'temp' variable, displaying the first initial.
