1\$\begingroup\$ The 0b prefix might not be supported by this particular compiler or it is configured to disable support for it. They are usually non-standard extensions and became standard around C++14. \$\endgroup\$– JustmeCommented May 7, 2021 at 11:37

Compiler does not seem to support 0b prefix for entering numbers in binary. You need to convert it to something else, like hex or decimal.
