Implement A Two Nested Loop In Rust

Rust allows for a variety of complex operations thanks to the expressive syntax. Implementing nested loops in Rust is a straightforward process. Let’s take a look at what this entails.

Code Snippet: Implementing a Two Nested Loop in Rust

fn main() {
    for i in 1..5 {
       for j in 1..5 {
          let result = i * j;
          println!("{} times {} = {}", i, j, result);
       }
    }
}

Code Explanation for Implementing a Two Nested Loop in Rust

This brief tutorial will break down the code snippet above in a step-by-step fashion to aid with understanding its components and functioning.

1. Firstly, we define the main function which is the primary function in Rust programs.

fn main() {

2. We create our first for loop with a range from 1 to 5 excluding 5. Here ‘i’ is the variable where the value will be stored for each iteration of the loop.

for i in 1..5 {

3. Within the first loop, we create a second loop. This is a nested loop. This nested loop also has a range from 1 to 5 (excluding 5), and ‘j’ is the variable in which the value of each loop iteration will be stored.

for j in 1..5 {

4. Inside these nested loops, we perform a multiplication operation. We are multiplying the values of ‘i’ and ‘j’ and storing it into the variable ‘result’.

let result = i * j;

5. Then we use the println macro to print the values of ‘i’, ‘j’, and ‘result’. ” {}” is a placeholder in our statement which will be replaced by variables preceding the string. The variables ‘i’, ‘j’ and ‘result’ will replace each {} from left to right.

println!("{} times {} = {}", i, j, result);

6. Finally, we close the brackets for the nested loop and the main function.

}
}

This results in Rust running the nested loop, creating a multiplication table for 1 to 4, and printing each result on the console. You can further modify and expand the ranges or the operation to suit your specific purposes when using Rust.
