Calculate sum for all the array elements.

Sum of Array Example Program

/*##Sum of Array In C++*/
/*##Calculation Programs In C++, Array Example Programs In C++*/

// Header Files
#include <iostream>
#include<conio.h>

using namespace std;

#define ARRAY_SIZE 5

int main()
{
    int array[ARRAY_SIZE];
    int i;
    float total = 0.0, average;
 
	cout<<"Sum of Array In C++ Example Program\n";
    
    for (i = 0; i < ARRAY_SIZE; i++)
    {
		cout<<"Enter the Number : "<< (i+1) <<"  : ";
        cin>>array[i];
    }
    
    /*  Sum of the Array Using for Loop */
    for (i = 0; i < ARRAY_SIZE; i++)
    {
        total = total + array[i] ;
    }
    average = total / ARRAY_SIZE;
    
    cout<<"\n Sum of all Numbers =  "<< total<<"\n";
    cout<<"\n Average of all input numbers =  "<< average<<"\n";
    
    getch();
}

Sample Output

Enter the Number : 1  : 6
Enter the Number : 2  : 7
Enter the Number : 3  : 8
Enter the Number : 4  : 2
Enter the Number : 5  : 3

Sum of all Numbers =  26.000000

Average of all input numbers =  5.20
