Write the c++ program that will create the one-dimensional array of random integer numbers of the size provided by the user and will search it (using the linear search, i.e. by checking all elements one by one) in order to find the particular value. The search should be done by the special function called inside the every iteration of the loop (for each element), returning the information about whether it is the searched element or not. Each function call should be registered by the static variable. The search function should be able to perform the operation left to right or right to left, depending on the users choice. Information returned by the program should include the index of the searched element (which is obviously related to the number of search function calls, stored inside the static variable).
