Rust program to calculate the area of a triangle for a given base and height

Given base and height of a triangle, we have to calculate the area of a triangle using Rust program.
Last Updated : September 29, 2021

Problem Statement

Here, we will read the base and height of the triangle from the user. Then we will calculate the area of the triangle and print the result.

Program/Source Code

The source code to calculate the area of a triangle for a given base and height is given below. The given program is compiled and executed successfully.

// Rust program to calculate the area of a 
// triangle for a given base and height

use std::io;

fn main() 
{
    let mut height:f32 = 0.0;
    let mut base: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 height: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    height = input2.trim().parse().expect("Not a valid number");
    
    area=(base * height) / 2.0;
    
    println!("Area of a triangle: {}", area);
}

Output

Enter base: 
12
Enter height: 
7
Area of a triangle: 42

Explanation

Here, we read the base and height from the user. Then we calculated the area of the triangle and printed the result.
