In Linux, suppose a process successfully opens an existing file that has a single hard link to it, but while the process is reading that file, another process unlinks that file? What happens to subsequent reads by the first process? Do they succeed? Do they fail? (Answer this problem by consulting documentation or by writing a program to test the behavior of the system in this case.)

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits.now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order.finally, output thedigits in thearray.use at least two functions to organize your program.
