C++

Write a program which reads content from two files and writes the output to a third file. Your program should read in two files each of which contains one number of type int per line. The numbers from each line of each file should be added together and the sum written to the output file. For example, if the first line of the first file contains a 1 and that of the second a 2, you should write 3 to the output file. Ensure that each sum appears on a new line in your output file
