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
using Second for loop the element is searched in each location from 0 to the location of element or location n-1.
if element is found in a location that location i is stored as pos and exit from the for loop using break statement.
if element is not found from 0 to n-1 location, pos remains -1.
