Web#include unsigned int bits_per_byte = CHAR_BIT; unsigned int bits_per_integer = CHAR_BIT * sizeof (int); The identifier CHAR_BIT represents the number of bits in a char. The sizeof returns the number of char locations occupied by the integer. Multiplying them gives us the number of bits for an integer. Share Improve this answer Follow WebJun 18, 2024 · Return Value: The function returns the number of set bits. It returns the total number of ones or the number of set bits in the binary representation of the number if the passed number is an integer. Below programs illustrates the bitset::count () function. Program 1: #include .
