Algorithm Determining leap year

- If the year is divisible by 100, then the year should also divisible by 400

Following algorithm:

1. Enter the (year)
2. If the rest of the division (the year divided by 4)! = (not equal to) 0, then print ("Year", the year, "not a leap year")
Otherwise
3. If the rest of the division (the year divided by 100) = (equal to) 0 and the rest of the division (the year divided by 400)! = (not equal to) 0, then print ("Year", the year, "not a leap year)
otherwise
4. If it does not meet all the conditions above, print ("Year", the year, "is a leap year")

Following implementation of the program:

01    #include <cstdlib>
02    #include <iostream>
03   
04    using namespace std;
05   
06    int main(int argc, char *argv[])
07    {
08        int tahun;
09        cout<<"Masukan tahun : ";
10        cin>>tahun;
11        cout<<endl;
12        if(tahun%4!=0)
13        cout<<"Tahun "<<tahun<<" Bukan tahun kabisat\n\n";
14        else if((tahun%100==0)&&(tahun%400!=0))
15        cout<<"Tahun "<<tahun<<" Bukan tahun Kabisat\n\n";
16        else
17        cout<<"Tahun "<<tahun<<" Adalah tahun kabisat\n\n";
18   
19        system("PAUSE");
20        return EXIT_SUCCESS;
21    }
