C++ please

Write a program that merges the numbers in two files. The program reads input from two different files and save the output to a singly linked-list. Each input file contains a list of integers in ascending order, that is, they start small and get bigger as they go, e.g. as the screenshots below. The input files should be named numbers1.txt and numbers2.txt numbers1.txt numbers2.txt 1 5 6 23 67 89 101 134 345 456 29 65 98 100 Your program should first read numbers from each file and generate two singly linked-lists, in the same order of input files. The program then needs to merge two linked-lists into one linked-list. After merge, the two input linked-list will becomes empty. The combined list should contain all numbers and also be in ascending order. The program should generate output to show the process of merging, like what I did in the sample output below (some of the outputs were removed on purpose and your program should show the whole process). The program should finally display the three lists after merging
