What to choose text or binary file?

Question

Database

I started to write something like a subd in C. And I ran into the question of where to store data in a text file or a binary one, so that the program can then parse the data at the user's request? I'm worried about what will be more efficient in terms of memory and speed.

Answer 1

The binary is faster and more compact. Text is more convenient to process with external tools, but slow and cumbersome.

Answer 2

Certainly binary.
