c/c++ string

1.本章思维导图：



Example1:
char
*strcpy(char *target, const char *source) {
  char *t = target;

  // Copy the contents of source into target.
 
while(*source) *target++ = *source++;
  // Null-terminate the
target.
  *target = '\0';
  // Return pointer to the
start of target.
  return t;
}
Example2:
void
*memmove(void *target, const void *source, size_t count)
这个函数即使
是在源和目的字符串有所重叠时操作也能成功，虽然source为const，但是其指向的array也可能被修改。
