dari hasil diatas maka tampilan gui adalah seperti
berikut ini :
dari hasil diatas kita coba untuk melakukan running
dari data yang telah kita buat,sebagai contoh kita coba memasukkan contoh data tinggi
badan semisal 175 seperti dibawah ini:
maka setelah kita running atau HITUNG maka hasil yang kita
dapatkan adalah :
terima kasih....dan selamat mencoba..
kritik dan saran sangat dinantikan….
