Input the length and breadth, find the area of the rectangle using Rust program.
Submitted by Nidhi, on September 26, 2021

Problem Solution:

Here, we will read the value of length and breadth from the user and calculate the area of the rectangle.

Program/Source Code:

The source code to calculate the area of the rectangle is given below. The given program is compiled and executed successfully.

// Rust program to calculate the 
// area of rectangle

use std::io;

fn main() {
    let mut length:f32 = 0.0;
    let mut breadth:f32 = 0.0;
    let mut area:f32 = 0.0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
    
    println!("Enter length: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    length = input1.trim().parse().expect("Not a valid number");

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

    area = length * breadth;
 
    println!("Area of rectangle: {}",area);
}

Output:

RUN 1:
Enter length: 
5.7
Enter breadth: 
3.4
Area of rectangle: 19.38

RUN 2:
Enter length: 
10
Enter breadth: 
20
Area of rectangle: 200

RUN 3:
Enter length: 
10.5
Enter breadth: 
5.10
Area of rectangle: 53.55

Explanation:

Here, we read the value of length and breadth from the user and calculated the area of the rectangle. After that, we printed the result.
