Write a program to read four floating points numbers and find their sum and average?

Answer 1

#include<stdio.h>

#include<conio.h>

int main(void)

{

float a,b,c,d,avg=0;

clrscr();

printf("\n Enter the four floating point nos.\n");

scanf("%f%f%f%f",&a,&b,&c,&d);

avg=(a+b+c+d)/4;

printf("\n the average is=%10.5f",avg);

getch();

return 0;

}

Answer 2

import java.util.Scanner; // necessary to use Scanner

public class AskForStuff {

public static void main (String [ ] input) {

Scanner keyboard = new Scanner(System.in);

String person;

int numArms;

double gpa;

// get user to give name

System.out.print("What is your name? ");

person = keyboard.nextLine();

// get the user's number of arms

System.out.print("How many arms do you have? ");

numArms = keyboard.nextInt();

// get the user's GPA

System.out.print("Give your GPA: ");

gpa = keyboard.nextDouble();

// now print back what we just received

System.out.println(person + " has " + numArms

+ " arms.");

System.out.println("The GPA of " + person +

" is " + gpa + ".");

}

}

Answer 3

#include <iostream>

using namespace std;

int main()

{

double x[4], total;

cout << "Enter 4 floating point numbers: " << endl;

for(int i = 0; i < 4; i++)

{

cin >> x[i];

total += x[i];

}

cout << "Total: " << total << " Avarage: " << total / 4 << endl;

char wait;

cin >> wait;

return 0;

}

Answer 4

float a, b, c, d, sum, mean;

scanf ("%f %f %f %f", &a, &b, &c, &d);

sum = a + b + c + d;

mean = sum / 4.;

printf ("sum: %f mean: %f\n", sum, mean);
