②按unsigned int格式转换存入时,如过大溢出则会保留低位(如62则会保留低5位,即11110,30) ③按字符串格式存入时,如溢出则会对字符串剩余部分进行截断 1strings ="1010";2bitset <5> b1;//默认为全03bitset <5> b2(10);//将unsigned int值转换为二进制数,再进行存储4bitset <5> b3(s);//将字符串...

只有当bitset的大小<=对应的大小(to_ulong为unsigned long,to_ullong为unsigned long long)时,才能使用这两个操作 例如: //在64位机器上,long long 0ULL是64位的,因此~0ULL是64个1 std::bitset<128> bitvec3(~0ULL); //0~63位为1,63~127位为0 unsigned long ulong = bitvec3.to_ulong(); std:...

12.BitSet get(int fromIndex, int toIndex) 返回一个新的 BitSet由 BitSet从 fromIndex （含）到 toIndex （独家）的位组成。 13.int hashCode() 返回此位集的哈希码值。 14.boolean intersects(BitSet set) 如果指定的 BitSet任何位设置为 true true在此 BitSet中也设置为 true ，则返回true。 15....
bitset类型在定义时就需要指定所占的空间,例如 bitset<233>bit; bitset类型可以用string和整数初始化(整数转化成对应的二进制) #include<iostream>#include<bitset>#include<cstring>usingnamespacestd;intmain() { bitset<23>bit (string("11101001")); ...
