Question

Which is better #define or enum?

Answer 1

• If we let it, the compiler can build enum values automatically. However, each of the defined values must be given separately.
• Because macros are preprocessors, unlike enums, which are compile-time entities, the source code is unaware of these macros. So, if we use a debugger to debug the code, the enum is superior.
• Some compilers will give a warning if we use enum values in a switch and the default case is missing.
• Enum always generates int-type identifiers. The macro, on the other hand, allowed us to pick between various integral types.
• Unlike enum, the macro does not have a defined scope constraint.
