printf("Enter size of array:");
printf("Enter %d Elements:",n);

calloc() is predefined function allocates memory of specified bytes.
Number of bytes is specified as (4,n), it means n 4 bytes. Since we are using integers, specified as 4bytes.
*a denotes first four bytes, *(a+1) denotes second four bytes, *(a+2) denotes third four bytes and so on.,
i is initialized to 0 and incremented by 1 at each iteration of both the for loops.
First for loop reads n input numbers from user and stores them in array a from location 0 to n-1
Second for loop adds all the n elements of array located from 0 to n-1
Finally prints the sum using printf statement.
