Thanks man, you helped me a lot.

[@shmeowlex]

Glad I could help!

Nice. But i dont think you should exit with a return 0. You could return with -1 or EXIT_FAILURE

[@priscusemmanuel8403]

I need help sir, I am using a MacBook Pro and I can't open these files or create one for that matter, I would appreciate your help

[@Itisnot2late]

Thanks! It helped me a lot.

[@shmeowlex]

Glad it helped!

[@Evizzo]

is there a function build in or something so i aim at certain string/line of txt file with fstream ?

[@shmeowlex]

No, you would need to read through the file

[@MementoMoriMementoVivere881]

I have a question. What if your input and output files are the same? I mean like the results of your input has to be added to the same file?

[@shmeowlex]

you would need to read everything in from the file into arrays, then output everything with the appended data.

[@Little_G_Dizzle]

I have one question: after making the file, where does it get stored? I am using an arduino R3 and a SD card as my source of storage, how do I move the file to an external drive?

[@shmeowlex]

I am not familiar with the arduino platform unfortunately :(

[@timog7358]

great video

Glad you enjoyed it

Why does the info get deleted when I run the program again even though I wrote endl at the end? and how do I prevent that from happening?

[@shmeowlex]

output files get deleted and recreated every time you open them.

[@lemniscate23]

Very helpful

[@shmeowlex]

Glad to help.

[@elaine3867]

Is there a need to check if the output file exists? Because from what I know, the output file will be created automatically in the project folder if it does not exist

[@shmeowlex]

If the path to the file is invalid it will fail (i.e. if you wanted to place your output in an output directory but the output directory was not created yet).

[@elaine3867]

@@shmeowlex Understood, thanks!

[@mr.shredder5430]

why are you using return 0 on if statement, i cannot get the logic?

[@shmeowlex]

To terminate the program.
