INPUT's:
1) Name
2) Current date (month, day, year)
3) Birthday (month, day, year)
The output will be the person's age in years, months, and days. See example below:
Input name: shane
Input current date:
Month (1-12): 9
Day (1-31): 25
Year (yyyy): 2010
Input birthday:
Month (1-12): 9
Day (1-31): 4
Year (yyyy): 1978
shane, you are now 32 year(s), 0 month(s), and 21 day(s) old.
So?
pls try
#include "stdio.h"
#include "conio.h"
int ay,yil,gun,a,y,g,guns,ays,yils;
main()
{
a=9; // todays month //
g=27; // todays day
y=2010; // todays year
printf("enter the day ");scanf("%d",&gun);
printf("enter the month:");scanf("%d",&ay);
printf("enter the year:");scanf("%d",&yil);
if(gun>g) {
g=g+30;
a=a-1;
guns=g-gun;
}
else guns=g-gun;
if(ay>a) {
a=a+12;
y=y-1;a
ays=a-ay;
}
else ays=a-ay;
yils=y-yil;
printf("day difference= %d month difference=%d year difference=%d",guns,ays,yils);
getche();
return 0;
}^ Ouch!
pls try
#include "stdio.h" #include "conio.h" int ay,yil,gun,a,y,g,guns,ays,yils; main() { a=9; // todays month // g=27; // todays day y=2010; // todays year printf("enter the day ");scanf("%d",&gun); printf("enter the month:");scanf("%d",&ay); printf("enter the year:");scanf("%d",&yil); if(gun>g) { g=g+30; a=a-1; guns=g-gun; } else guns=g-gun; if(ay>a) { a=a+12; y=y-1;a ays=a-ay; } else ays=a-ay; yils=y-yil; printf("day difference= %d month difference=%d year difference=%d",guns,ays,yils); getche(); return 0; }
Wow you are such a clever person!
no I found this script in turkish website. it is not mine
