bitset::size() is a built-in STL in C++ which returns the total number of bits.
Parameter: The function accepts no parameter.
Return Value: The function returns an integral value which signifies the number of bits. It eventually returns the size that has been given while initializing the bitset.
Below programs illustrate the bitset::size() function.
The number of bits in 1100 is 4 The number of bits in 010010 is 6
The number of bits in 101 is 3 The number of bits in 10001 is 5
