Rust program to demonstrate the nested while loop

Rust | Nested while Loop Example: Using the nested while loop, we have to print the tables from 2 to 5.
Submitted by Nidhi, on October 05, 2021

Problem Solution:

In this program, we will use a nested while loop to print tables from 2 to 5.

Program/Source Code:

The source code to demonstrate the nested while loop is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate the 
// nested "while" loop

fn main() {
    let mut cnt1:i32 = 2;
    let mut cnt2:i32 = 0;
    
    while cnt1<=5
    {
        cnt2=1;
        while cnt2<=10
        {
            print!("{} ",(cnt1*cnt2));
            cnt2=cnt2+1;
        }
        cnt1=cnt1+1;
        println!();
    }
}

Output:

2 4 6 8 10 12 14 16 18 20 
3 6 9 12 15 18 21 24 27 30 
4 8 12 16 20 24 28 32 36 40 
5 10 15 20 25 30 35 40 45 50 

Explanation:

Here, we used the nested while loop to print tables from 2 to 5.
