Write a program that calculate Average of Four Numbers in C++

Calculate average of four numbers and print the numbers and their deviation from the Average

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

#include <iostream.h> #include <iomanip.h> #include <conio.h> int main () { cout << "\nEnter the First number : "; int num1; cin >> num1 ; cout << "\nEnter the Second number : "; int num2; cin >> num2 ; cout << "\nEnter the Third number : "; int num3; cin >> num3 ; cout << "\nEnter the Fourth number : "; int num4; cin >> num4 ; int sum = num1 + num2 + num3 + num4; float average = sum /4.0 ; cout << fixed ; cout << showpoint; cout << setprecision (2); cout << "\n ******** Average is " << average << " ******** \n"; cout << "\n First no : " << num1 << " -- Deviation : " << setw(8) << (num1 - average) ; cout << "\n Second no : " << num2 << " -- Deviation : " << setw(8) << (num2 - average) ; cout << "\n Third no : " << num3 << " -- Deviation : " << setw(8) << (num3 - average) ; cout << "\n Fourth no : " << num4 << " -- Deviation : " << setw(8) << (num4 - average) ; getch(); return 0; }//main

Output:

Enter the first number  : 24

Enter the second number : 56
 
Enter the third number  : 46

Enter the fourth number : 24

******** Average is 37.50 ********

 First  no : 24 -- Deviation :        -13.50
 Second no : 56 -- Deviation :         18.50
 Third  no : 46 -- Deviation :          8.50 
 Fourth no : 24 -- Deviation :        -13.50
