How Can I Use Binary Literals in C and C ?

Binary Literals in C and C

Working with binary numbers in C or C can be a challenge. One approach is to use hexadecimal numbers, which have the same value as binary numbers but are expressed in a different base. However, this requires some conversion calculations, which can be cumbersome.

If you are using the GNU Compiler Collection (GCC) compiler, there is a more elegant solution: binary literals.

Using Binary Literals in GCC

GCC provides an extension for binary literals, which was later adopted into the C 14 standard. Binary literals are prefixed with 0b, followed by the binary digits. For example:

int x = 0b00010000;

This line of code declares an integer variable x and assigns it the binary value 00010000.

Note: Other compilers, such as Clang and MSVC, do not support binary literals directly. If you need to use binary literals with non-GCC compilers, you will need to use a third-party library or implement your own conversion function.
