Refer to function bitCount(). Which statement about the returned value 'count' is true?

Explanation:
The function bitCount() reports how many bits are 1 in the value’s binary form. In other words, it counts the positions in the value’s binary representation that are set to 1. This is known as the population count of the value. It is not the total number of bits that the type could hold (that would be a fixed width like 32 or 64). It is not the number of 0 bits, which would be the width minus the number of 1 bits. It also isn’t about decimal digits at all—the decimal representation has no direct bearing on the binary bit count.
