C++ Exercises: Compute the total and average of four numbers

C++ Basic: Exercise-30 with Solution

Write a program in C++ to compute the total and average of four numbers.

Pictorial Presentation:

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

    int main()
    {
    	float n1,n2,n3,n4,tot,avrg;
		cout << "\n\n Compute the total and average of four numbers :\n";
		cout << "----------------------------------------------------\n";		
        cout<<" Input 1st two numbers (separated by space) : ";
    	cin>> n1 >> n2;
        cout<<" Input last two numbers (separated by space) : ";
    	cin>> n3 >> n4;
    	tot=n1+n2+n3+n4;
		avrg=tot/4;
        cout<<" The total of four numbers is : "<< tot << endl;
        cout<<" The average of four numbers is : "<< avrg << endl;
        cout << endl;
        return 0;
    }

Sample Output:

 Compute the total and average of four numbers :                       
----------------------------------------------------                   
 Input 1st two numbers (separated by space) : 25 20                    
 Input last two numbers (separated by space) : 15 25                   
 The total of four numbers is : 85                                     
 The average of four numbers is : 21.25
