#include "time.h"

int main(int argc,char *argv[]){

char s[19];

int y,t,ty;

time_t lt;

printf("Please enter your ID number...\n");

if(scanf("%18s",s)==1){

for(t=0;s[t];t++);

if(t==18){

for(t=0;s[t];t++)

if((s[t]<'0' || s[t]>'9') && (s[17]&0xDF)!='X'){

printf("Input error, exit...\n");

return 0;

}

sscanf(s+6,"%4d",&y);

printf("\nThe year %d you were born is ",y);

if(!(y%4==0 && y%100 || y%400==0))

printf("not ");

ty=localtime(&(lt=time(NULL)))->tm_year+1900-y;

printf("a leap year.\nYou're %d year(s) old...\n",ty);

}

else

printf("Input error, exit...\n");

}

printf("Input failed, exit...\n");

return 0;
