factorialfunction

Function named factorial() takes input of positive integer and shows its factorial If a positive integer is not entered, the function will keep on taking an input until a positive integer is entered. To reduce the size, u32 variables are used hence you can enter from 0 ~ 12 to get factorial. Function will return the factorial of the value entered by you.

To use this library you have to add following line in [dependencies] section of Cargo.toml

factorialfunction = "0.1.0"

In src/main.rs you can use like this:

use factorialfunction;
fn main() {
    println!("Hello, world!");
    factorialfunction::factorial();
}

now cargo run for results
