Basic data type:
1) plastic types: int, short int, long int, long long int (c99), char, bool.
2) Floating-point type: float, double and double-precision floating-point type (float _ complex, double _ complex, long long _ complex).
2.bitset type exists in C++ and bitset type exists in C/C++, which is easier to use than bit operation.
Bitset is a class library of C++ language, which is used to manage a series of bits conveniently without the need for programmers to write their own codes. Bitset can not only access the bits with specified subscripts, but also use them as an integer for some statistics.
