Pada postingan kali ini, sebenarnya hanya mempublikasikan tugas yang diberikan salah satu dosen saya . . .

Sebenarnya, tidak perlu diposting, cukup dikumpulkan saja,,,tetapi

alangkah baiknya juga saya posting di blogger saya ini,,,

alhamdulillah, jika ada juga orang lain mencari berupa tugas ini ,,,

berbagi ilmu dan juga kebaikan...

wahhh,,,ada juga sih yang agak gagal,,tapi gak pa2....perbaiki sendiri ya,,,

gue (sok gaul) juga copy paste,,,,hehehe

kan ada mbah google...sayangkan gak dimanfaatkan . . . . ..

wahhhhh,,,,,,gak usah panjang lebar ya sama dengan luas persegi panjang...
aheheheee,,,, bercanda.....

ini langsung aja beberapa syntax untuk kalkultaor

1. pertama-tama buka terlebih dahulu notepad anda dan ketik (copy & paste) pada tulisan di bawah ini
2. simpan dengan memberikan nama yang anda inginkan
3. pahami isinya,,mungkin ada kegagalan
4. selesai
