Rust program to find the square of a given number using a generic function

Find the square of a given number using a generic function

Rust Programming Language

Problem

In this program, we will create a generic function to calculate the square of a given number and print the result.

Input

// Rust program to find the square of a given number 

// using a generic function

use std::ops::Mul;

fn getsquare<T: Mul<Output = T> + Copy> (num: T) -> T {

    return num * num;

}

fn main() {

    let sqr1 = getsquare(6);

    println!("Square is: {:?}", sqr1);

    

    let sqr2 = getsquare(6.23);

    println!("Square is: {:?}", sqr2);

}{codeBox}

Output

Square is: 36

Square is: 38.812900000000006{codeBox}

Explanation

In the above program, we created a generic function to calculate the square of the given number. The generic function is given below,

fn getsquare<T: Mul<Output = T> + Copy> (num: T) -> T {

    return num * num;

}{codeBox}

In the main() function, we called the getsquare() function and printed the square of the specified number.
