请问oled显示程序为什么有两段一样的程序，它们分别有什么作用呢

Question

 int main(void)
  {    u8 t;
        delay_init();            
        NVIC_Configuration();     
    delay_ms(8000);
        OLED_Init();    
        OLED_Clear()      ; 
    
        t=' ';
        OLED_ShowCHinese(0,0,0);//ÖÐ
                OLED_ShowCHinese(18,0,1);//¾°
        OLED_ShowCHinese(36,0,2);//Ô°
        OLED_ShowCHinese(54,0,3);//µç
        OLED_ShowCHinese(72,0,4);//×Ó
        OLED_ShowCHinese(90,0,5);//¿Æ
        OLED_ShowCHinese(108,0,6);//¼¼
    while(1) 
    {        
        OLED_Clear();
        OLED_ShowCHinese(0,0,0);//ÖÐ
        OLED_ShowCHinese(18,0,1);//¾°
        OLED_ShowCHinese(36,0,2);//Ô°
        OLED_ShowCHinese(54,0,3);//µç
        OLED_ShowCHinese(72,0,4);//×Ó
        OLED_ShowCHinese(90,0,5);//¿Æ
        OLED_ShowCHinese(108,0,6);//¼¼

想问一下为什么main函数里在while之前也要运行一段和while中完全一样的ShowChinese程序呢，它们的作用不一样吗？

Answer 1

显然这并不是一段很好的代码
