Rust program to find the Surface Area and Volume of the Cylinder

Program/Source Code:

The source code to find the Surface Area and volume of the cylinder is given below. The given program is compiled and executed successfully.

// Rust program to find the Surface 
// Area and volume of the cylinder

use std::io;

fn main() 
{
    let mut radius:f32    =0.0;
    let mut height:f32    =0.0;
    let mut area:f32    =0.0;
    let mut volume:f32    =0.0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
       
    println!("Enter radius: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    radius = input1.trim().parse().expect("Not a valid number");
    
    println!("Enter height: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    height = input2.trim().parse().expect("Not a valid number");
    
    volume = 3.14 * radius * radius * height;
    area   = 2.0 * 3.14 * radius * (radius + height);
    
    println!("Volume of Cylinder is: {}", volume);
    println!("Surface area of Cylinder is: {}", area);
}

Output:

Enter radius: 
5
Enter height: 
3.2
Volume of Cylinder is: 251.2
Surface area of Cylinder is: 257.48

Explanation:

Here, we read the radius, height from the user. Then we calculated the surface area and volume of the Cylinder and printed the result.
