Module 3

< Unix 에서 Compile하기>

1. Complie
#aCC datatype.C => a.out 실행파일 생성
2. 실행
#./a.out

=> Default Include Directory
/usr/inclue/CC/*
/usr/include/*

=> Default Library
/usr/lib/libC.a

3. option
#CC datatype.C -o datatype // 실행파일이름
#CC -g datatype.C // debugger 정보
#CC datatype.C -I/home/user01/utils // include 지정
#CC datatype.C -L/home/user01/utils
-lxm // library :libxm.a libxm.sl
#CC -v datatype.C // verbose

.C
=> Compile
=>.o (object file)
=> linker(ld)
=>a.out (실행 파일)

<Operator >
1 .Unary Operator
2. Binary Operator
1> Arithmetic Operator
+ - * / %(modulus)
int x = 9, y=2;
int z = x / y; // 몫 4
z= x % y; // 나머지 1
2> Assignment
=
+= int x =10;
x = x+10; // x += 10;
3> Relational Operator => true(!0 - 1)/false(0)
== != < > <= >=
int x = 10;
if (x == 10) // true
4> Logical Operator
&& - short curcuiting ( T T T)

int x =10, y=8;
if ((x++ <10) && (y++ <10))
{
}

|| (F F F)
!



3. Ternary Operator
? :




<loop >
- break
- continue -> pass to 조건 check

<preprocessor>
1. #include
#include <date.h > system include directory
-I$HOME/utils
2. Conditional Compilation

#ifndef DATE_H
#define DATE_H
....
#endif

#ifdef DEBUG
..
#endif

< Microsoft Visual C++ >
1. C/C++ Complier
ANSI C , ANSI C++
ANSI (America National Standard Institute)

2. SDK (Software Development Kit)
- API (Application Programming Interface)
- function <- by Windows OS
- Windows 95/98/ME
- \windows\system\kernel32.dll
gdi32.dll
user32.dll
- Windows NT/2000
\winnt\system32\ .........
- C-style function

3. MFC (Microsoft Foundation Class Library)
- API => Class 화
- 300 classes

4. Developer Studio
5. Tools - debugger, spy,tracer .......

Complie => .obj
