temperature measuring instrument pcba java

Write a program in Java to store 20 temperatures in °F in a Single Dimensional Array (SDA) and display all the temperatures after converting them into °C.

Hint: (c/5) = (f - 32) / 9

Answer

import java.util.Scanner; public class KboatSDAF2C { public static void main(String args[]) { Scanner in = new Scanner(System.in); double arr[] = new double[20]; System.out.println("Enter 20 temperatures in degree Fahrenheit"); for (int i = 0; i < arr.length; i++) { arr[i] = in.nextDouble(); } System.out.println("Temperatures in degree Celsius"); for (int i = 0; i < arr.length; i++) { double tc = 5 * ((arr[i] - 32) / 9); System.out.println(tc); } } }
