If the program does not use ob_strat() to open the buffer, what will be the effect of using ob_end_flush() directly later? Does it have the same effect when used together with ob_start()?

ob_start() and ob_end_flush() can control the output when used in pairs.
ob_strat() opens the buffer, ob_end_flush() outputs the buffer content and closes the buffer.
ob_end_flush is invalid when used alone.
