cHow to find the sum of all the elements of an integer array?
int sum(int arr[], int n) {
int sum = 0;
for (int i=0; i<n; i++)
sum += arr[i];
return sum;
}ctrl + cint arr[]The name of the integer array of which sum is to be calculated | int nNumber of elements in the array named arr |
forFor loop in C through which we can iterate multiple number of times | |
Usage example
#include <stdio.h>
int sum(int arr[], int n) {
int sum = 0;
for (int i=0; i<n; i++)
sum += arr[i];
return sum;
}
int main() {
int my_array[9] = {1, 2, 3, 4, 6, 7, 8, 9, 10};
int number_of_elements = 9;
printf("%d: is the sum of the given array", sum(my_array, number_of_elements));
return 0;
}output
50: is the sum of the given arrayMore of C
