bitset::test() is an inbuilt function in C++ STL which tests whether the bit at a given index is set or not.
Parameters: The function accepts only a single mandatory parameter index which specifies the index at which the bit is set or not.
Return Value: The function returns a boolean value. It returns true if the bit at the given index is set else it returns false.
Below programs illustrate the above function:
Bit at index 2 of 1100 is set Bit at index 3 of 010010 is not set
Bit at index 2 of 5 is set Bit at index 3 of 16 is not set
