/* program in c for addition of elements in array. */

Description :

We are going to add the elements of array and store it in a variable. and finally we shall display the results.

Logic :

Initialize sum = 0. We shall read first number for user and add it with value in sum variable. then we shall read next number for user and add it with value in sum variable. and continue it till the last element. Finally sum variable will contain the sum of all elements.

Program :

#include<stdio.h>
#include<conio.h>
void main()
{
  int i,n;
  int arr[20],sum=0;
  printf("Enter the number of element in array : ");
  scanf("%d",&n);
  for(i=0;i<n;i++)
  {
    printf("Enter %d element in array : ");
    scanf("%d",&arr[i]);
    sum = sum + arr[i];
  }
  printf("The sum of all elemnt is %d. ",sum);
  getch();
}

Output :

C program for sum of array. Tested in Turbo C 3.2
