Hello. I am currently on ex17 and I notice the use of ‘FILE’ and ‘struct’. In this particular example, the first place I see this is
Struct Connectio n{
FILE *file;
Struct Database *db;
};
Can anyone help me understand the difference?

This should have been covered earlier, shouldn’t it?
FILE*
is a pointer to a stream handle, which is the type of object that all the I/O functions use to interact with input/output streams. stdout
is a FILE*
, just like the things you get by any call to fopen
. See also here.
A struct
is the compound type in C, comparable to objects in JavaScript and dictionaries in Python, with the big difference that a struct always contains a predefined number of things of a predefined type.
Does that help?
