i want to know that in a c++ code during execution how iostream file is founded. we write #include in c++ program and i know about #include which is a preprocessor directive to load files and is a file name but i don't know that how that file is located. i have some questions in my mind...

Is Standard library present in compiler which we are using?
Is that file is present in standard library or in our computer?
Can we give directory path to locate the file through c++ code if yes then how?
