2. Physical data structure & Logical data structure

1. Physical : for storing the data [1] Array A collection of continous memory locations, all these locations are side by side. This array will have fixed size, once it is created of some size, then that size cannot be increased or decreased. The size of array is fixed. An array can be created either inside stack or heap. When should I use it? When you are sure, what is the maximum number of elem..

1. Stack vs Heap

1. About Main Memory Memory is divided into smaller addressable units that are called as bytes. Every bytes have its own address. The entire memory is not used as a single unit, but it is divided into manageble pices, that are called as segment. 2. How a Program use memory Main mamory is divided into three sections : code section, Stack, and Heap. If I have a program file on the hard disk and if..

[Algorithm & Data structure] Introduction

Data is an integral part of an applications or programs. 1. what is data structure? Data structure : arrangement of collection of data items so that they can be utilized efficiently, operations on that data can be done efficiently inside the main memory during the execution of a program. That is, during the execution of a program how the grogram will manage data inside the main memory and perfor..

[C++ summary ]

Arrays : a collection of similar data elements The main memory is divided into three sections. 1. Code section 2. Stack 3. Heap The array will be created inside the stack. Tht will be directly accessible to the main function. ex) int a[5]; [Initializer of array] int b[5] = {2, 4, 6, 8, 10}; Structures : a collection of data members Pointer : an address variable stroing address of data pointer ta..

[C++] Code::Blocks - WinMain@16 에러 해결하기

헤더파일과 소스파일로 파일분할을 할 때 Code::Blocks IDE를 사용했을 때 "undefined reference to 'WinMain@16'"이라는 에러가 떴는데 이를 해결하기 위한 방법을 찾아보았을 때 Stack Overflow에서는 Compiler setting에서 Build option을 바꾸면 해결될거라고 했으나 이는 문제를 해결하지 못하였다. 그리고 Link의 문제이기 때문에 프로젝트 내에서 각 파일을 생성하면 된다는 얘기를 들었고 Dev-C++ IDE를 사용하여 프로젝트를 생성하고 프로젝트 내에서 파일을 포함시켰더니 오류가 발생하지 않았다. Code::Blocks IDE가 동일 폴더 내부에 있는 파일을 Link로 연결시키지 못해서 발생하는 문제라고 생각된다.

[C language] Reading a File to the End

Formatted Input  Check the return value of scanf in a while loop: while (scanf("%d", &n) == 1)  Do not use !=, but use == for the condition. => " "를 기준으로 다른 명령문을 처리함. e.g ) while(scanf("%s", word) == 1) { if (isalpha(word[0])) { printf("%c", upper(word[0])) } } I am two apples => IATA (맨 앞 글자만 대문자로 바꿔줌) Character-Based Input  Check the return value of getchar against EOF in a while loop: whil..
