Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
  
   int *p,n,i,sum=0;
   printf("Enter the size of Array Here\n");//Ask the user to size of the array
   scanf("%d",&n);
  
   p=(int*)malloc(n*sizeof(int));//this is for dynamic memory
   //now ask the values from the user
   printf("Enter the array values below:\n");
   for(i=0;i<n;i++)
   {
       printf("Enter number %d:",i+1);
       scanf("%d",(p+i));
   }
   //now sum calculation is here
   for(i=0;i<n;i++)
   {
       sum=sum+*(p+i);
   }
   //Now we have to print the sum
   printf("\nSum is:%d",sum);
   //now we have to free the memory by using free
   free(p);
  
}

Output:
