Write C Program to Calculate Addition of All Elements in Array

Program : Addition of All Elements of the Array

#include <stdio.h>

int main() {
   int i, arr[50], sum, num;

   printf("\nEnter no of elements :");
   scanf("%d", &num);

   //Reading values into Array
   printf("\nEnter the values :");
   for (i = 0; i < num; i++)
      scanf("%d", &arr[i]);

   //Computation of total
   sum = 0;
   for (i = 0; i < num; i++)
      sum = sum + arr[i];

   //Printing of all elements of array
   for (i = 0; i < num; i++)
      printf("\na[%d]=%d", i, arr[i]);

   //Printing of total
   printf("\nSum=%d", sum);

   return (0);
} 

Output :

Enter no of elements : 3
Enter the values : 11 22 33
a[0]=11
a[1]=22
a[2]=33
Sum=66
