Question
The program allowed the user to enter the values of a,b, and c into the array. Once the user has entered the input, the program
The program allowed the user to enter the values of a,b, and c into the array.
Once the user has entered the input, the program displays the solutions to the quadratic equation.
Attached is a program written by one of your classmates.
There is one compilation errors and one run-time error in the program.
After you fix the errors. Try running the program with input
a=1, b= -3 , and c= 2
The expected output is Sol1= 2 and Sol2= 1
But the actual output is Sol1= -1 and Sol2= -2
This is a case of Logic error
Which statement needs to be modified?
The error is in a line that is between lines 12 and 15.
the program is:
import java.util.Scanner; public class MyCalculator { public static void main(String args[]) { Scanner input = new Scanner (System.in); int array[3] ; System.out.println("Enter a:"); array[0]= input.nextInt(); System.out.println("Enter b:"); array[1]= input.nextInt(); System.out.println("Enter c:"); array[3]= input.nextInt(); int b = array[1]; double squreRoot = Math.sqrt( Math.pow(array[1], 2 - (4*array[0]*array[2]) ) ; double sol1= ( b + squreRoot) / (2*array[0]) ; double sol2= ( b - squreRoot) / (2*array[0]) ; System.out.printf("Sol1: %d ",(int)sol1); System.out.printf("Sol2: %d ",(int)sol2); } }
