Write C program to find sum of all elements of an array
#include <stdio.h> #define MAX_SIZE 100 //Maximum size of the array int main() { int arr[MAX_SIZE]; int i, num, sum=0; //Reads size and elements in array printf("Enter size of the array: "); scanf("%d", &num); printf("Enter %d elements in the array: ", num); for(i=0; i<num; i++) { scanf("%d", &arr[i]); } //Adding all elements for(i=0; i<num; i++) { sum = sum + arr[i]; // Calculating sum } printf("Sum of all elements of array = %d", sum); return 0; }
