Question: 1 / 565

What happens if you attempt to modify a const variable?

Compiler warning

Compiler error

A A compiler warning will not stop the program from executing, but it is not possible to modify a constant variable, so it would be futile.

C: A runtime error would occur if the program attempted to access or modify a memory location that it does not have permission to, which would not be the case with modifying a const variable.

D: Undefined behavior could potentially occur if attempting to modify a const variable, as different compilers may handle this differently. However, the most common and expected outcome would be a compiler error.

Therefore, the best answer is B: Compiler error, as attempting to modify a const variable is not allowed and will result in a compilation error.
