5.2. Amaliy qism: Tananing vazn ko`rsatkichini hisoblash
Key Point. Ichma-ich if operatoridan foydalanib tananing vazn ko`rsatkichi (TVK)ni hisoblovchi dastur tuzish mumkin
Insonning tana vazn ko`rsatkichi – uning vazni va bo`yining uzunliklariga asoslanib hisoblangan salomatlik koeffisientidir. Insonning salomatlik koeffisientini hisoblash uchun uning kilogramlardagi og`irligini metrlardagi bo`yi o`lchamining kvadratiga bo`lish kerak. 20 yoki undan katta yoshdagi insonning salomatligini hisoblash talqini quyidagicha:
