why double Quotations instead of angle brackets?

Question

I saw in examlpes, the header file of the written class was included like this: #include "MYCLASS.H",
but the other statement is like this #include <iostream>, so why they didn't add it like this #include <MYCLASS.H>?

Answer 1

this is because MYCLASS.H is in the same folder as the program and is being included relatively however if it had been linked by the compiler it would be in <> because the compiler knows where to look for it
