berikut adalah program penghitung umur sederhana dengan bahasa C, program ini akan menanyakan nama user, lalu meminta input tanggal lahir dan sekarang, sekaligus memberi komentar










#include <stdio.h>
#include <stdlib.h>
#include <string.h>
/*age counter program*/

int main()
{
/*variable declaration*/
char name[32];
int bday, bmonth, byear;
int tday, tmonth, tyear;
int tdate, bdate;
int day, month, year;

/*user input*/
printf ("who are you \n");
scanf ("%s[^\n]", name);

/*input birth day*/
printf ("input birth day \n");
scanf ("%d", &bday);
printf ("input birth month \n");
scanf ("%d", &bmonth);
printf ("input birth year \n");
scanf ("%d", &byear);

/*input recent day*/
printf ("input recent day \n");
scanf ("%d", &tday);
printf ("input recent month \n");
scanf ("%d", &tmonth);
printf ("input recent year \n");
scanf ("%d", &tyear);

/*algorhytm processing*/
bdate=bday+(bmonth*30)+(byear*365);
tdate=tday+(tmonth*30)+(tyear*365);

/*result processing*/
year=(tdate-bdate)/365;
month=(tdate-bdate)%365/30;
day=(tdate-tmonth)%365%30;

/*result*/
printf("%s %d %d %d", name, day, month, year);

/*comment about age*/
if (year <= 5) {
printf ("\n you're still baby \n");
}
else if (year <= 17) {
printf ("\n you're still young\n");
}
else if (year <= 40) {
printf ("\n you're an adult \n");
}
else if (year <= 99) {
printf ("\n you're old enough \n");
}
else {
printf ("\n are you serious? \n");
}


getchar();
return 0;
}
