Char

Part of the Fundamentals section of Coddy's Rust journey — lesson 6 of 75.

A char is a single character (For example: 1, 6, %, b, p, ., T, etc.)

The char type is a special type that consists of a single character.

To initialize a char value in a variable, enclose it within single quotation marks:

let c1: char = 'h';

In the above example, a char variable named c1 is initialized.

Challenge

Beginner

Store the char C in a variable named initial.

Cheat sheet

A char is a single character data type that stores one character (letters, numbers, symbols, etc.).

To declare a char variable, use single quotation marks:

let c1: char = 'h';

Try it yourself

fn main() {
    // Type your code below
    let initial: char = ?;
    
    // Don't change the line below
    println!("initial = '{}'", initial);
}
