Declare a structure "Student" which contains the following information:
1
i.
ii.
Student ID
Grade for 5 subjects
2. Write a function to
i
search for a Student ID and if exists write "Found", otherwise, write "Not Found"
Write the Student found (ID and Grade) to a file with file name "StudentFile.txt
In the main (0 function:
3.
i
ii.
ii.
Read the data of an array of 10 students from the user (i.e., keyboard)
Read from the user a student ID to search for
Invoke the function search to search for the Student ID read by the user

Yes, I know the answer. So do many, many other people here.

You have to write some code to accomplish what is specified in this "assignment".

Pay special attention to the first part of that answer. "YOU have to write some code..."

Nobody is going to write this for you.

Haven’t seen any standard term. If you need such term, I’d rather go for “inclusion point”. The word “reference” has many uses and adding another one is not going to make things clearer.

Anyway it has no direct relation to the linker. It is purely a textual inclusion and it will go through preprocessor and compiler before.

Sorry, I don't understand what you try to accomplish. Are you trying to document how your library has to be used by a client program? In this case, I've seen instructions like:
"... place an include directive to <cool_library.h> in your program"

or even:
"... place an include directive to <cool_library.h> before the include directive for <not_so_cool.h>"

If you are looking for something else, try to explain more.

It is still not clear what you mean by "the process". There is no process as such, you just need to ensure that the compiler can find all declarations and/or definitions of any functions that you are trying to use. Either within your source file or in an associated header.

Re: terminology refresher class ??

The source code may be using definitions of classes/functions etc in an external library. The header file provides this information so the compiler can create a reference in the object code. Such references will then be used by the linker to fix the links to a library or other object code module. For example given the followin directory structure:

PROJECT
    LIB
    CLIENT

you might have:

C++

// Library.h the defintions of the library, in the LIB subdirectory
void Foo(char* name);

// Library.c the implementation of the library, in the LIB subdirectory
void Foo(char* name)
{
    printf("Hello, World! A message from %s\n", name);
}

//Implementor.cpp the program that will use the library, in the CLIENT subdirectory
#include "../LIB/Library.h"
int main(int argc, char** argv)
{
    Foo("fred");

    return 0;
}

Does that make sense?

Maybe because your question did not clearly define what you were looking for.

The build process gets the #include of the library but fails to find the

I am a little confused by some of your terminology, and also it is unclear which system you are using for the build. So a few possible ideas:
1. If this is using Visual Studio on Windows, you can add the locations of include directories to the Project settings. The compiler will search all such locations for include files.
2. If you are using a Makefile then add the include locations to the CPPFLAGS macro in the form "-I <include location>".
3. If the location of one of the headers is relative to the current directory then you can add the details to the #include statement thus:

C++

#include "subdir\library.h"

4. If it is something else then please provide the details.
