Rust program to calculate the area of Parallelogram

Program/Source Code:

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

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

use std::io;

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

    area = base * altitude;
    
    println!("Area of Parallelogram is: {}", area);
}

Output:

Enter base: 
12.34
Enter altitude: 
34.56
Area of Parallelogram is: 426.47043

Explanation:

Here, we read the value of base, altitude from the user. Then we calculated the area of Parallelogram and printed the result.
