bool
areEqual(
uint64_t const* bitString1,
std::size_t index1,
uint64_t const* bitString2,
std::size_t index2,
std::size_t numBits);Return true if the specified numBits beginning at the specified index1 in the specified bitString1 are bitwise equal to the numBits beginning at the specified index2 in the specified bitString2, and false otherwise. The behavior is undefined unless bitString1 has a length of at least index1 + numBits and bitString2 has a length of at least index2 + numBits.
true if the compared bits are equal, and false otherwise
| Name | Description |
|---|---|
| bitString1 | first bit string |
| index1 | starting bit index in bitString1 |
| bitString2 | second bit string |
| index2 | starting bit index in bitString2 |
| numBits | number of bits to compare |
