Rust program to multiply two numbers using '+' operator

Given two numbers, we have to multiply them using '+' operator using Rust program.
Submitted by Nidhi, on September 28, 2021

Problem Solution:

Here, we will read two numbers from the user. Then we will multiply both numbers using the '+' operator and print the result.

Program/Source Code:

The source code to multiply two numbers using '+' operator is given below. The given program is compiled and executed successfully.

// Rust program to multiply two numbers 
// using '+' operator

use std::io;

fn main() {
    let mut n1:u32 = 0;
    let mut n2:u32 = 0;
    let mut cnt:u32 = 1;
    let mut mul:u32 = 0;
    let mut res:u32 = 0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
    
    println!("Enter number1: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    n1 = input1.trim().parse().expect("Not a valid number");

    println!("Enter number2: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    n2 = input2.trim().parse().expect("Not a valid number");

    
    while(cnt<=n2)
    {
        mul += n1;
        cnt = cnt+1;
    }
        
    println!("Multiplication is: {}",mul);
}

Output:

RUN 1:
Enter number1: 
10
Enter number2: 
20
Multiplication is: 200

RUN 2:
Enter number1: 
6
Enter number2: 
4
Multiplication is: 24

Explanation:

Here, we read the value of n1, n2 from the user. Then we multiplied both numbers using the the '+' operator and printed the result.
