L4 COMP 348 Functions (C) questions
with complete solutions
What type of language is C - correct answer ✔✔Imperative and procedural
Imperative languages use what and what can they do - correct answer ✔✔Series of statements, which

The code in C is organized around what - correct answer ✔✔Logical functionality Functions in C associated with a certain task are organized into what - correct answer ✔✔A single source file Examples in C of functions associated with a certain task that are organized into a single source file - correct answer ✔✔IO functions, database functions, graphics functions Are source files compiled separately? Then what? - correct answer ✔✔Yes, then linked together into a single executable What is the advantage of having source files compiled separately and then linked together into a single executable? - correct answer ✔✔This allows changes to large programs to be made much more efficiently Use of makefiles - correct answer ✔✔When large applications require a lot of files, it is a very complex build environment. Makefiles use a special syntax to define how C/C++ source files should be compiled and linked into a single application or library Gcc invocation to compile several source files into a single executable - correct answer ✔✔gcc file1.c file2.c myApp.c Can you use this invocation with large or smaller orograms? And why? gcc file1.c file2.c myApp.c - correct answer ✔✔Inly smaller programs, bc it compiles several source files into a single executable. Large programs have too many source files. Which of the three files contains a main function in this invocation? gcc file1.c file2.c myApp.c - correct answer ✔✔myApp.c True or false: with multiple source files, functions in one file will be invoked from functions in other source files - correct answer ✔✔True

  1. If the API changes you would have to update every one of the calling source files Example of API changing - correct answer ✔✔The function name is modified The proper way to manual inclusion - correct answer ✔✔Create header files that expose the API of the functions that are going to be used elsewhere How do you do your own version of the standard header file like <stdio.h> - correct answer ✔✔By creating header files that expose the API of the functions that are going to be used elsewhere How do you create header files that expose the API of the functions that are going to be used elsewhere
  • correct answer ✔✔Create a new file and add the prototypes to this file. What type of files end with a .h suffix in C - correct answer ✔✔Header file What is the header file's name - correct answer ✔✔The same as the source file it supports Application source file example for creating a header file - correct answer ✔✔#include <stdio.h> #include "file1.h" void my_method () { int y = do_something(4); } What should have been done if we didn't assume that all files are in the same folder as the source file - correct answer ✔✔Additional path info would need to be added with the #include directive What does providing the compiler with a list pf additional include directories do - correct answer ✔✔It allows the compiler to find user-defined header files, just like it finds the standard headers

What should a header file look like - correct answer ✔✔#ifndef file1_H_ #define file1_h_ Int do_something(int x) #endif What do conditional cpp directives do - correct answer ✔✔They ensure that only one copy of this header file gets included in your source file Examples of conditional cpp directive - correct answer ✔✔#endif #ifndef file1_H_ What is a header guard - correct answer ✔✔Only one copy of the header file gets included in your source file Why is conditional inclusion important - correct answer ✔✔Bc multiple inclusions of the same header file into a single source file can cause compilation problems True or false: multiple inclusion is hard to do - correct answer ✔✔False Can header files be included in many different source files, including other header files? - correct answer ✔✔Yes The header guards are used for - correct answer ✔✔To create a cpp flag that says this header has been included during the current compilation phase What would happen if the same header is encountered again by the header guard - correct answer ✔✔Its inclusion would be skipped

What is the static specifier for in C - correct answer ✔✔To modify visibility, used to qualify function definitions What happens when we use a static function - correct answer ✔✔It tells the compiler that this function can only be referenced/invoked from the source file in which it is written Can you make a static function externally visible, how - correct answer ✔✔Yes, by associating its return value to a "public" data type Is there an order that we should put functions in C - correct answer ✔✔No Can you invoke a function in the same source file if the comoiler has not seen the function declaration already - correct answer ✔✔No Can you invoke a function in the same source file if the comoiler has seen the function declaration already - correct answer ✔✔Yes What would happen if you try to invoke a function if the compiler has not seen the function declaration already - correct answer ✔✔You will get standard warning about implicit declaration Should the helper function be first - correct answer ✔✔Yes, Should you include a prototype for helper() at the top of the source file - correct answer ✔✔Yes Where are header files included in - correct answer ✔✔The source file associated to it A header file uses what to include its own prototypes - correct answer ✔✔A cpp directive Should static functions be included in the header file - correct answer ✔✔No

Why shouldn't static functions be included in the header file - correct answer ✔✔Bc these functions are not part of the API What would happen if we put a static function on the header file, why - correct answer ✔✔Function not defined warning bc the compiler will fail to find a function to match the prototype What should be done when you add a prototype for a static function in the current source file - correct answer ✔✔Both the prototype and the full function definition should include the static specifier What heppens if you add a prototype for a static function in the current source file but the prototype and the full function definition don't include the static specifier - correct answer ✔✔The compiler will consider them to be different functions and warnings/errors will occur
