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
