what is literal in c++

• Can literals be used as non-type template arguments?
• Assuming that the order of user-defined literal application is predictable in all cases.
• Forgetting that user-defined literal suffixes offer a way to create more self-documenting code by attaching semantic meaning to literal values, reducing the need for extensive comments or external documentation to explain their purpose and units.
• How do user-defined literals interact with implicit conversions?
• Is '0xA' a literal in C++?
• Assuming that literal operators can be declared within class definitions (they must be free functions or member templates of the same class).
• Are standard-layout types always literal types?
• Forgetting that user-defined literal suffixes are a compile-time construct and do not exist at runtime unless a corresponding variable or object holds the result of the literal operator.
• Assuming that literal operators can be used to create literals that represent physical quantities with automatic unit conversions at compile time (though user-defined types and operators can facilitate this).
• Assuming that literal operators can be used to create literals with custom ABI representations.
