Using pointers and dynamic memory allocation: design, build, and compile and run a c++ program including a function searchn() to search a one-dimensional array x of size n for a specific value using pointer notation. the function should return how many times the key value is present in the array and the location of the first occurrence of the key value in the array. write a main() function to prove your function. display all output in your main program. nothing should be displayed in the function.
