Rust Program: Define character variable with first initial
Rust Variables and Data Types: Exercise-9 with Solution
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.
