This course provides the best approach to learn Rust, starting from the basics and advancing to complex topics. It is an introduction to Rust for beginners aspiring to become skilled Rust developers.

The word is out: developers love Rust. It's rapidly becoming a top choice for systems and embedded programmers, and the demand for Rust developers is rising. Known for its performance, reliability, and productivity—especially compared to C++—Rust is a powerful language to master. If you're a systems developer, it's a fantastic next step.
In this course, you'll learn Rust by actively engaging in coding. You’ll start with a simple "Hello world" program and cover essential concepts like arrays, strings, vectors, enums, structures, traits, generics, functions, and logic. You'll also dive into advanced topics such as lifetime and memory management.
By the end of this course, you'll have a solid foundation in Rust programming and be well-prepared to take on more advanced concepts, making it ideal for Rust beginners looking to become proficient Rust developers.

Rust Programming Language

fn test(n:i32) {
    // define a nested for loop
    for i in 0..n { //outer loop
        for j in 0..i + 1 { // inner loop
            print!("&");
    }
    println!("");
    }
}
fn main(){
    println!("Right angled triangle when n = 5 ");
    test(5);
    println!("Right angled triangle when n = 6 ");
    test(6);
}

## Explanation
> The value `n` is given to you for which the right-angled triangle needs to be printed.

**nested `for` loop**
  * On **line 3**, in the **outer `for` loop**
     * An iterator `i` iterates over the **range 
      0 to  `n`.**
   *  On **line 4**, for each `i`, within the  **inner `for` loop**, an iterator `j` iterates over the **range 0 to `i` + 1**
       * In each iteration, it prints the character `&`  within the **`print!`** macro on **line 5**.
       * When **`j` equals `i+1`, the inner loop breaks** and the control goes to outer `for` loop.
* When the inner `for` loop terminates **`println!("")`** appends **a new line**.
* When the value of **`i` equals `n`, the outer loop terminates**.
* The output is a right-angled triangle.
