컴파일 (17) 썸네일형 리스트형 The C Preprocessor The C PreprocessorThe C preprocessor modifies a source code file before handing it over to the compiler. You're most likely used to using the preprocessor to include files directly into other files, or #define constants, but the preprocessor can also be used to create "inlined" code using macros expanded at compile time and to prevent code from being compiled twice. There are essentially three u.. Formatting Cout Output in C++ using iomanip Formatting Cout Output in C++ using iomanipCreating cleanly formatted output is a common programming requirement--it improves your user interface and makes it easier to read any debugging messages that you might print to the screen. In C, formatted output works via the printf statement, but in C++, you can create nicely formatted output to streams such as cout. This tutorial covers a set of basi.. 레슨 20: Inheritance - Syntax Lesson 20: Inheritance - Syntax Before beginning this lesson, you should have an understanding of the idea of inheritance. If you do not, please read lesson 19. This lesson will consist of an overview of the syntax of inheritance, the use of the keywords public, private, and protected, and then an example program following to demonstrate each. The syntax to denote one class as inheriting from an.. 레슨 18: Binary Trees in C++: Part 1 Binary Trees in C++: Part 1The binary tree is a fundamental data structure used in computer science. The binary tree is a useful data structure for rapidly storing sorted data and rapidly retrieving stored data. A binary tree is composed of parent nodes, or leaves, each of which stores data and also links to up to two other child nodes (leaves) which can be visualized spatially as below the firs.. 레슨 17: Functions with variable-length argument lists Lesson 17: Functions with variable-length argument lists Perhaps you would like to have a function that will accept any number of values and then return the average. You don't know how many arguments will be passed in to the function. One way you could make the function would be to accept a pointer to an array. Another way would be to write a function that can take any number of arguments. So yo.. 레슨 16: Recursion Lesson 16: Recursion Recursion is a programming technique that allows the programmer to express operations in terms of themselves. In C++, this takes the form of a function that calls itself. A useful way to think of recursive functions is to imagine them as a process being performed where one of the instructions is to "repeat the process". This makes it sound very similar to a loop because it r.. 레슨 15: Singly linked lists Lesson 15: Singly linked lists Linked lists are a way to store data with structures so that the programmer can automatically create a new place to store data whenever necessary. Specifically, the programmer writes a struct or class definition that contains variables holding information about something, and then has a pointer to a struct of its type. Each of these individual struct or classes in .. 레슨 14: Accepting command line arguments Lesson 14: Accepting command line arguments In C++ it is possible to accept command line arguments. Command-line arguments are given after the name of a program in command-line operating systems like DOS or Linux, and are passed in to the program from the operating system. To use command line arguments in your program, you must first understand the full declaration of the main function, which pr.. 이전 1 2 3 다음
