Did you know?
WebYou may assume that lowbit and highbit are both greater than or equal to 0 and less than or equal to 31. If lowbit > highbit, then the returned mask should be all zero. For … WebFungsi 4 : bitMask(highbit,lowbit) Fungsi bitMask menghasilkan suatu mask dimana seluruh bit antara highbit dan lowbit diset menjadi 1, dan bit sisanya diset menjadi 0. Asumsi 0 <= lowbit <= 31 dan 0 <= highbit <= 31. Jika lowbit > highbit, mask seluruhnya 0. Contoh : bitMask(5,3) = 0x38 Prototype fungsi : int bitMask(int highbit, int lowbit)
