        在uCos ii中，就緒組、就緒表是比較基礎的概念。理解其含義，對於理解uCos ii 的任務管理、事件管理至關重要。        就緒組，本質上就是一個8位無符號變數。就緒組變數的每一個bit位代表一組8個任務中是否有就緒的任務。uCos 賦予這個變數以特殊的意義：當其bit0 為1時，代表任務0~任務7中至少有一個任務就緒了；當其bit1 為1時，代表任務8~任務15中至少有一個任務就緒了......當其bit7

toupper, tolower地球人都知道 C++ 的 string 沒有 toupper ，好在這不是個大問題，因為我們有 STL 演算法：string s("heLLo");transform(s.begin(), s.end(), s.begin(), toupper);cout << s << endl;transform(s.begin(), s.end(), s.begin(), tolower);cout << s << endl;

distance很多時候我們希望在一個 vector ，或者 list ，或者什麼其他東西裡面，找到一個值在哪個位置，這個時候 find 幫不上忙，而有人就轉而求助手寫迴圈了，而且是原始的手寫迴圈：for ( int i = 0; i < vect.size(); ++i)    if ( vect[i] == value ) break;如果編譯器把 i 看作 for scope 的一部分，你還要把 i 的聲明拿出去。真的需要這樣嗎？看看這個：    int dist =        

主函數中調用外部檔案定義的函數，兩種方法：第一種：htest.cpp:#include "stdafx.h"#include "stdio.h"extern void b(void);extern void c(void);int main(int argc, char* argv[]){printf("Welcome to main.\n");b();c();return 0;}a.cpp:#include "stdio.h"void b(void){printf("b() in a.cpp

1、正常讀寫pointertest.cpp:#include "stdafx.h"#include "stdio.h"int main(int argc, char* argv[]){int a[]={11,12,13,14,15,16};int *p;p=a;for(int i=1;i<7;i++,p++)*p=i+10;p=a;for(int j=1;j<7;j++,p++)printf("%d\n",*p);return 0;}2、越界讀、正常寫pointertest.cpp:

1、後++MacroTest1.cpp:#include "stdafx.h"#include "stdio.h"#define program(x) ((x)*(x)*(x))int main(int argc, char* argv[]){int i=3;printf("i:%d\n",i);int j=program(i++);printf("j:%d\n",j);printf("i:%d\n",i);return
