In the folder I have TEXT files named as PPT1.TXT, PPT2.TXT,PPT3.TXT...., PPT16.TXT. I want to read these files and do some operations like, adding one more column and then save to a new location with same name as PPT1.TXT, PPT2.TXT.... I wish to use a variable for naming these files and do the operation on them as I can just change the name of the variable at one place in the code and the code should should be able to read the correct desired file(PPT1.TXT) and write to the file with the desired name(PPT1.TXT).
But if I put the variable name inside '' (apostropes) in textscan and fprintf commands, it throws error.
Can you please help me with this?
