Write a C/C++ program which implements the following functionality
1) Read two files simultaneously(we will modify this to make more generic later)
2) File A contains the list of strings and file B is regular text file
3) Read the string mystr(for eg) from File A and search for it in File B
4) Each occurrence of mystr in File B should be replaced with mystr-<suffix>
5) A new File B_Mod should get generated with all the string replaced.
