#include "lib.h"#include <stdio.h>void main(void){struct time t;
t.ti_hour=12;
t.ti_min=12;while(1){
t.ti_sec=62;if( checktime(&t )== OK )printf("\fTime ok!!\n");elseprintf("\fIllegal time!!");while(!kbhit())
idle();
resetkey();
t.ti_sec=12;if( checktime(&t )== OK )printf("\fTime ok!!\n");elseprintf("\fIllegal time!!");while(!kbhit())
