Objective:

Write a C program that takes as input two lists of integers (in increasing order) and creates combines the numbers in third list of ordered numbers. The two input lists shall be read from separate text files and the combined list shall be written to an output file.

Specifications:

1. The files that the program uses will have the following names: "Data1.txt", "Data2.txt", and "Merged.txt". Note: Your program will be used with the grader's data files. If your program does not use the correct file names, then it will not run successfully.

2. The program will check for failures opening the files and will provide a graceful exit if a failure exists.

3. The program will have appropriate programmer-defined functions so that the main function provides a highlight of the program.

4. The program will have a comment block at the top of the file with your name, the course number, the date the program was completed, and a brief description of the program.

Note: You are not allowed to read all of the data into a single array and use a sorting function. Try to think of a more efficient approach.
