1.Suppose all required files are present, and I run the makefile successfully. Now I modify mp3.h. Assume that there is no error after modification. What are the files that get regenerated?

2. Suppose I realize that I need to add some constants in mp3utils.c whose declarations are found in new header.h header file. I make the appropriate changes in mp3utils.c (assume there is no error in the new C-code I write). But I am not sure where I should put the newheader.h file in the above makefile. Suggest where the newheader.h file should be put in the above make file.

3.Suppose I run make clean. What is the problem I will encounter in subsequent compilations of my code?
