finding sum of an array code example
Example 1: how to add up all numbers in an array
var numbers = [10, 20, 30, 40]
var sum = 0;
for (var i = 0; i < numbers.length; i++) { sum += numbers[i]}
Example 2: sum of arrays
#include <stdio.h>
#define MAX_SIZE 100
int main()
{
int arr[MAX_SIZE];
int i, n, sum=0;
printf("Enter size of the array: ");
scanf("%d", &n);
printf("Enter %d elements in the array: ", n);
for(i=0; i<n; i++)
{
scanf("%d", &arr[i]);
}
for(i=0; i<n; i++)
{
sum = sum + arr[i];
}
printf("Sum of all elements of array = %d", sum);
return 0;
}
