array sum of elements code example
Example 1: array sum javascript
const arr = [1, 2, 3, 4];
const sum = arr.reduce((a, b) => a + b, 0);
Example 2: sum of an array
const sum = (...args) => args.reduce((a, b) => a + b, 0);
console.log(sum(1,2,3));
Example 3: js array sum
console.log(
[1, 2, 3, 4].reduce((a, b) => a + b, 0)
)
console.log(
[].reduce((a, b) => a + b, 0)
)
Example 4: 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]);
sum += arr[i];
}
printf("Sum of all elements of array = %d", sum);
return 0;
}
Example 5: 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;
}
