How to print Left Half Pyramid Pattern in Rust

How to print Left Half Pyramid Pattern in Rust ?

Answer

To print the Left Half Pyramid Pattern in Rust, we use nested loops where the outer loop controls the rows and the inner loop prints spaces and stars.

✐ Examples

1 Left Half Pyramid Pattern

In this example,

We define the size of the pyramid, n, which is set to 5 in this example.
We use two nested loops: an outer loop to handle rows and an inner loop to print spaces and stars.
The outer loop runs from 1 to n, controlling the number of rows.
The inner loop in Rust prints spaces based on the difference between n and the current row, followed by stars equal to the current row number.
This combination of loops and print statements creates the Left Half Pyramid Pattern.

Rust Program

fn main() {
    let n = 5;
    for i in 1..=n {
        let spaces = " ".repeat(n - i);
        let stars = "*".repeat(i);
        println!("{}{}", spaces, stars);
    }
}

Output
