Bitcount c言語
WebJava Integer bitCount() method. The bitCount() is a method of Integer class under java.lang package. It returns the number of one-bits in the two's complement binary representation of the specified int value. This function is sometimes referred to as the population count. Syntax. Following is the declaration of bitCount() method: Webint bitcount(unsigned long n) { const static unsigned char aa[] = { 0, 1, 1, 2, 1, 2, 2, 3, 1, 2, 2, 3, 2, 3, 3, 4 }; for (int c = 0; n; n >>= 4) { c += aa[n & 0xf]; } return c; } ちょっと長くなり …

WebBitcount is a cross-platform implementation of GCC's intrinsic __builtin_clz, __builtin_ctz, and __builtin_popcount. Currently only intrinsic functions are used in VS 2012 (possibly older VS versions as well), and GCC-compatible compilers (including Clang). If Bitcount is used on a system that isn't either of these, it uses a C implementation ... http://hp.vector.co.jp/authors/VA000092/win32/technique.html
