[ACM] Modular thinking

 

 

流畅敲出

内存拷贝

#include <string.h>

char* strcpy (char* des,      const char* source)
char *strncpy(char *destinin, char *source,       int maxlen);
void *memcpy (void *destin,   void *source,       unsigned n);

 

小窗口判断

char *pPre = nullptr;
char *pNow = nullptr;
for (int i = 0; i < loop_size; ++i)
{   
    pPre = pDat + i;
    pNow = pDat + i + 1;
    char preChar = *pPre;
    char nowChar = *pNow;
