Programming Project 4 Attached Files: LinkedList.h (3.457 KB) D another client and output.txt(1.331 KB) Implement linkedList class. The header file, linkedList.h is given. (with conditions) In class, we will try to implement some of them. You can create your own client program to test it. A simple client program, #include include "LinkedList"h" using namespace std int main linkedList 14st: 1ist.insertFirst (10) List.insertFirat (20) a iat.insertFirat (30) 2 list.print ) ist insertLast (40) list.printo system "pause") a return 0 will generate the following output. List has 3 items: 1301 1201 1101 ist has 4 itema: 1301 1201 (101 40) More test programs and expected output will be posted
