Sum of Array Example Program

/*##Sum of Array*/
/*##Calculation Programs, Array Example Programs*/

#include  <stdio.h>
#define ARRAY_SIZE 5
 
int main()
{
    int array[ARRAY_SIZE];
    int i;
    float total = 0.0, average;
 
    
    for (i = 0; i < ARRAY_SIZE; i++)
    {
		printf("Enter the Number : %d  : ", (i+1));
        scanf("%d", &array[i]);
    }
    
    /*  Sum of the Array Using for Loop */
    for (i = 0; i < ARRAY_SIZE; i++)
    {
        total = total + array[i] ;
    }
    average = total / ARRAY_SIZE;
    
    printf("\n Sum of all Numbers =  %f\n", total);
    printf("\n Average of all input numbers =  %.2f\n", average);
}

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
