54. Compile-Time Constant Check

You are given a program that contains a compile-time check:

static_assert(a == 12, "Failed");

Your job is to define a compile-time constant named a so that this static assertion succeeds.

• If a is not a compile-time constant equal to 12, the program will fail to compile.
• If correct, the program will compile and print:

  • passed 

This demonstrates how static_assert enforces configuration rules before the firmware even runs.

Example Output:

passed 

Constraints:

• a must be defined as a compile-time constant (constexpr or equivalent).
• Do not modify the static_assert inside main().
• Only write code in the marked section.
