8진수, 16진수의 이해 Understanding Different Base SystemsThis essay is targeted at new students of computer programming or computer science who want to understand how base two (binary), base eight (octal), and base sixteen (hexadecimal) work. First of all, it's important to realize that each of these base systems is just another way of writing down the same number. When you convert a number between different bases, .. 공감수 1 댓글수 0 2011. 6. 7.
2진 트리 검색 Binary Search Trees Binary search trees (also known as just binary trees) are ordered trees in which all nodes have no more than two children. The parent node is always greater than all of the data in the left sub-tree that extends from the left child node, and the parent node is less than all of the data in the right sub-tree that extends from the right child node. Here is the basic framwork fo.. 공감수 2 댓글수 0 2011. 6. 7.
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.. 공감수 1 댓글수 0 2011. 6. 7.
The C++ Modulus Operator The C++ Modulus OperatorTake a simple arithmetic problem: what's left over when you divide 11 by 3? The answer is easy to compute: divide 11 by 3 and take the remainder: 2. But how would you compute this in a programming language like C or C++? It's not hard to come up with a formula, but the language provides a built-in mechanism, the modulus operator ('%'), that computes the remainder that res.. 공감수 0 댓글수 0 2011. 6. 7.
Getting Random Values in C and C++ with Rand Getting Random Values in C and C++ with Rand Written by RoDAt some point in any programmer's life, he or she must learn how to get a random value, or values, in their program. To some this seems involved, difficult, or even beyond their personal ability. This, however, is simply not the case. Randomizing of values is, at its most basic form, one of the easier things a programmer can do with the .. 공감수 0 댓글수 0 2011. 6. 7.
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.. 공감수 2 댓글수 0 2011. 6. 7.
Enumerated Types - enums Enumerated Types - enumsSometimes as programmers we want to express the idea that a variable will be used for a specific purpose and should only be able to have a small number of values--for instance, a variable that stores the current direction of the wind might only need to store values corresponding to north, south, east, and west. One solution to this problem might be to use an int and some .. 공감수 1 댓글수 1 2011. 6. 7.
Class Design in C++ : Understanding Interfaces Class Design in C++Understanding InterfacesWhen you're designing a class in C++, the first thing you should decide is the public interface for the class. The public interface determines how your class will be used by other programmers (or you), and once designed and implemented it should generally stay pretty constant. You may decide to add to the interface, but once you've started using the cla.. 공감수 0 댓글수 0 2011. 6. 7.
Understanding Initialization Lists in C++ Understanding Initialization Lists in C++Understanding the Start of an Object's LifetimeIn C++, whenever an object of a class is created, its constructor is called. But that's not all--its parent class constructor is called, as are the constructors for all objects that belong to the class. By default, the constructors invoked are the default ("no-argument") constructors. Moreover, all of these c.. 공감수 0 댓글수 0 2011. 6. 7.
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.. 공감수 0 댓글수 0 2011. 6. 7.
레슨 19: Inheritance - An Overview Lesson 19: Inheritance - An Overview The ability to use the object-oriented programming is an important feature of C++. Lesson 12 introduced the idea of the class; if you have not read it and do not know the basic details of classes, you should read it before continuing this tutorial. Inheritance is an important feature of classes; in fact, it is integral to the idea of object oriented programmi.. 공감수 0 댓글수 0 2011. 6. 7.
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.. 공감수 2 댓글수 0 2011. 6. 7.
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.. 공감수 2 댓글수 0 2011. 6. 7.
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.. 공감수 2 댓글수 0 2011. 6. 7.
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 .. 공감수 2 댓글수 0 2011. 6. 7.
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.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 13: More on Functions Lesson 13: More on Functions In lesson 4 you were given the basic information on functions. However, I left out one item of interest. That item is the inline function. Inline functions are not very important, but it is good to understand them. The basic idea is to save time at a cost in space. Inline functions are a lot like a placeholder. Once you define an inline function, using the 'inline' k.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 12: Introduction to Classes Lesson 12: Introduction to Classes C++ is a bunch of small additions to C, with a few major additions. One major addition is the object-oriented approach (the other addition is support for *Generic programming, which we'll cover later). As the name object-oriented programming suggests, this approach deals with objects. Of course, these are not real-life objects themselves. Instead, these objects.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 11: Typecasting Lesson 11: Typecasting Typecasting is making a variable of one type, such as an int, act like another type, a char, for one single operation. To typecast something, simply put the type of variable you want the actual variable to act as inside parentheses in front of the actual variable. (char)a will make 'a' function as a char. For example: #include using namespace std; int main() { cout 공감수 2 댓글수 0 2011. 6. 7.
레슨 10: C++ File I/O Lesson 10: C++ File I/O This is a slightly more advanced topic than what I have covered so far, but I think that it is useful. File I/O is reading from and writing to files. This lesson will only cover text files, that is, files that are composed only of ASCII text. C++ has two basic classes to handle files, ifstream and ofstream. To use them, include the header file fstream. Ifstream handles fi.. 공감수 2 댓글수 1 2011. 6. 7.
레슨 9: C Strings Lesson 9: C Strings In C++ there are two types of strings, C-style strings, and *C++-style strings. This lesson will discuss C-style strings. C-style strings are really arrays, but there are some different functions that are used for strings, like adding to strings, finding the length of strings, and also of checking to see if strings match. The definition of a string would be anything that cont.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 8: Array basics Lesson 8: Array basics Arrays are useful critters because they can be used in many ways. For example, a tic-tac-toe board can be held in an array. Arrays are essentially a way to store many values under the same name. You can make an array out of any data-type including structures and classes. Think about arrays like this: [][][][][][] Each of the bracket pairs is a slot(element) in the array, a.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 7: Structures Lesson 7: Structures Before discussing classes, this lesson will be an introduction to data structures similar to classes. Structures are a way of storing many different values in variables of potentially different types under the same name. This makes it a more modular program, which is easier to modify because its design makes things more compact. Structs are generally useful whenever a lot of.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 6: An introduction to pointers Lesson 6: An introduction to pointers Pointers are an extremely powerful programming tool. They can make some things much easier, help improve your program's efficiency, and even allow you to handle unlimited amounts of data. For example, using pointers is one way to have a function modify a variable passed to it. It is also possible to use pointers to dynamically allocate memory, which means th.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 5: switch case in C and C++ Lesson 5: switch case in C and C++ Switch case statements are a substitute for long if statements that compare a variable to several "integral" values ("integral" values are simply values that can be expressed as an integer, such as the value of a char). The basic format for using switch case is outlined below. The value of the variable given into switch is compared to the value following each o.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 4: Functions Lesson 4: Functions Now that you should have learned about variables, loops, and conditional statements it is time to learn about functions. You should have an idea of their uses as we have already used them and defined one in the guise of main. cin.get() is an example of a function. In general, functions are blocks of code that perform a number of pre-defined commands to accomplish something pr.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 3: Loops Lesson 3: Loops Loops are used to repeat a block of code. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming -- many programs or websites that produce extremely complex output (such as a message board) are really only executing a single task many times. (They may be executing a small number of tasks, but in principle, to pr.. 공감수 2 댓글수 0 2011. 6. 7.
레슨 2 : If statements (if,else문) Lesson 2: If statements The ability to control the flow of your program, letting it make decisions on what code to execute, is valuable to the programmer. The if statement allows you to control if a program enters a section of code or not based on whether a given condition is true or false. One of the important functions of the if statement is that it allows the program to select an action based.. 공감수 2 댓글수 0 2011. 6. 7.
