Question

Write a java program to input the corresponding data to print the result of the following expression

Answer 1

Answer:

The program in Java is as follows:

import java.util.Scanner;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 float a, b, c, x, y;

 a = input.nextFloat();

 b = input.nextFloat();

 c = input.nextFloat();

 x = input.nextFloat();

 y = a * x * x + b * x + c;

 System.out.print(y); }}

Explanation:

This declares all variables

 float a, b, c, x, y;

The next 4 lines get input for a, b, c and x

 a = input.nextFloat();

 b = input.nextFloat();

 c = input.nextFloat();

 x = input.nextFloat();

This calculates the value of y using $y = ax^2 + bx + c$

$y = a * x * x + b * x + c;$

This prints the calculated value of y

 System.out.print(y);
