What is the difference between #include <filename> and #include "filename"?

Question

In the C and C++ programming languages, what is the difference between using angle brackets and using quotes in an `include` statement, as follows? 1. `#include <filename>` 1. `#include "filename"`

Answer 1

the angle brackets tell the compiler to look in an include directory buried somewhere in the

software's directory tree

the double quotes tell the compiler to find the header in a directory folder that YOU put it.
