What distinguishes #include "library.h" from #include <stdio.h> in C?
Brackets include implementation files.
Quotes for user-defined headers in current directory.
Brackets for standard libraries only.
Quotes search system paths first.
Why must function declarations go in a .h file for libraries in C?
To compile faster.
To store function definitions.
To define the interface for other files.
To prevent multiple inclusions.
What command links multiple C files into an executable?
g++ -o app main.c
gcc main.c library.c only.
cc -link main.c library.c
gcc -o app main.c library.c
In multi-file C programs, where are function implementations placed?
In the main function.
In the header file.
In the .c file for the library.
In a separate executable.
What error might occur if a function is declared in .h but not defined?
Linker error at compilation.
Runtime error only.
Syntax error immediately.
No error, it compiles fine.
