#include<stdio.h>
main()
{
    int d1,d2,m1,m2,y1,y2,D,M,Y;
    printf("Enter your Birthday-date,month,year\n");
    scanf("%d%d%d",&d1,&m1,&y1);
    printf("Enter today's date-date,month,year \n");
    scanf("%d%d%d",&d2,&m2,&y2);
    if(((d1<=d2)&&(m1<=m2))||(d1<=d2)||(m1<=m2))//default and the easy condition
    {
        D=d2-d1;
        M=m2-m1;
        Y=y2-y1;
    }
    if((d1>d2)&&(m1>m2))
    {
        D=30-d1+d2;
        M=12-m1+m2-1;
        Y=y2-y1-1;
    }
    if(d1>d2)
    {
        D=30-d1+d2;
        M=m2-m1-1;
        Y=y2-y1;
    }
    if((d1>d2)&&(m1==m2))
    {
        D=30-d1+d2;
        M=12-m1+m2-1;
        Y=y2-y1-1;
    }
    if(m1>m2)
    {
        D=d2-d1;
        M=12-m1+m2;
        Y=y2-y1-1;
    }
    if(y1==y2)
    {
        D=d2-d1;
        M=m2-m1;
        Y=0;
    }
    printf("Your age is %d years, %d months and %d days\n",Y,M,D);
}
