编辑：以你的标准考虑在内，我已经编辑了链接code这样：

Taking your specification into account, I've edited the code in the link to this:

char *replace_str(char *str, char *orig, char *rep, int start)
{
  static char temp[4096];
  static char buffer[4096];
  char *p;

  strcpy(temp, str + start);

  if(!(p = strstr(temp, orig)))  // Is 'orig' even in 'temp'?
    return temp;

  strncpy(buffer, temp, p-temp); // Copy characters from 'temp' start to 'orig' str
  buffer[p-temp] = '\0';

  sprintf(buffer + (p - temp), "%s%s", rep, p + strlen(orig));
  sprintf(str + start, "%s", buffer);    

  return str;
}
