Java HW(Need help ASAP)

Question

Write a program to prompt student for their name then test 1 grade, test 2 grade, test 3 grade.

Calculate the average grade and print a statement such as:

“Student name your grades are:

Test1 = grade1

Test2 = grade 2

Test3 = grade 3

Average = ave

Use printf to format average to 1 place after decimal point

Note: declare all grade variables double, and name variable as string

Answer 1

You say JAVA but then you say printf....

printf is C/C++ , not Java.

//** JAVA ****//

import java.util.Scanner;

class GradeAvg

{

public static void main(String args[])

{

(new GradeAvg()).Go();

}

public void Go()

{

String name;

int N=3;

double testScores[] = new double[N];

double testScoreAvg;

Scanner scanner = new Scanner(System.in);

System.out.print("Please input name :>");

name = scanner.nextLine();

double testScoreSum=0;

for (int iLoop=0; iLoop<3; iLoop++)

{

System.out.print(" Please input test score # " + (iLoop+1) + " :>");

testScores[iLoop] = scanner.nextDouble();

testScoreSum += testScores[iLoop];

}

System.out.println( name + " grades are:");

for (int iLoop=0; iLoop<N; iLoop++)

{

System.out.println(testScores[iLoop]);

}

testScoreAvg = testScoreSum/N;

System.out.println(" Average grade = " + testScoreAvg);

}

}

//C

#include <stdio.h>

#define NUM_TEST_SCORES (3)

Go()

{

char name[255];

int iLoop;

double testScores[NUM_TEST_SCORES];

printf(" Please input name :>");

scanf("%s",name);

double testScoreSum=0;

for (iLoop=0; iLoop<NUM_TEST_SCORES; iLoop++)

{

printf(" Please input test score # :>");

scanf("%lf",&testScores[iLoop]);

testScoreSum += testScores[iLoop];

}

printf(" %s grades are: \n",name);

for (iLoop=0; iLoop<NUM_TEST_SCORES; iLoop++)

{

printf("%6.2f \n",testScores[iLoop]);

}

double testScoreAvg = testScoreSum/NUM_TEST_SCORES;

printf(" average is %6.1f \n ",testScoreAvg);

}

main()

{

Go();

}
