Question

Light travels at 3 × 10⁸ meters per second. A light-year is the distance a light beam travels in one year.

Write a program that calculates and displays the value of a light-year.

Useful facts:

1. Seconds in a year = 365×24×60²
2. Rate = 3×10⁸ meters per second

Answer 1

One way you can do it is to begin by creating the known values as either as constants or variables.

Once you have the first two values then it's a matter of multiplying the seconds in one year times the rate. Then you store the value. Since there are no actual variables you don't need to create a function. You would need a function or method in Java or C# but not in something like Python or JavaScript.

let secondsInOneYear = 365*24*60*60;

let rate = 3 * Math.pow(10, 8);

let result = secondsInOneYear * rate;

Above is the example in JavaScript. Now you would just print it to the screen.

console.log(secondsInOneYear.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","))

console.log(rate.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","))

console.log(result.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","))
