C Exercises: Find the sum of all elements of an array
C Array: Exercise-3 with Solution
Write a program in C to find the sum of all elements of an array.
Pictorial Presentation:

Sample Solution:
#include <stdio.h>
void main()
{
int a[100];
int i, n, sum=0;
printf("\n\nFind sum of all elements of array:\n");
printf("--------------------------------------\n");
printf("Input the number of elements to be stored in the array :");
scanf("%d",&n);
printf("Input %d elements in the array :\n",n);
for(i=0;i<n;i++)
{
printf("element - %d : ",i);
scanf("%d",&a[i]);
}
for(i=0; i<n; i++)
{
sum += a[i];
}
printf("Sum of all elements stored in the array is : %d\n\n", sum);
}
Sample Output:
Find sum of all elements of array: -------------------------------------- Input the number of elements to be stored in the array :3 Input 3 elements in the array : element - 0 : 2 element - 1 : 5 element - 2 : 8 Sum of all elements stored in the array is : 15
