How Can I Check Bits in C/C Without Using Bitwise Operators?

Checking Bits Without Bitwise Operations

In C and C , bit manipulation operations are often utilized to check the values of individual bits within data variables. However, in certain scenarios, you may want to avoid explicit bit shifting and masking. Here's a discussion on how to achieve this:

C Macro

In C, you can define a macro to simplify the task without bitwise operations:

#define CHECK_BIT(var, pos) ((var) & (1 << (pos)))

To check if the nth bit from the right end is set to 1, use it as follows:

CHECK_BIT(temp, n - 1)

C bitset Library

C provides the std::bitset library, which offers a more user-friendly interface for bit manipulation. You can create a bitset using:

std::bitset<8> bitset(temp);

where 8 represents the number of bits in temp. The bitset class provides member functions such as test to check if a specific bit is set:

bitset.test(n - 1);

By leveraging these techniques, you can conveniently check bit values in C/C without relying solely on bitwise operations.
