what is literal in c++

• Not realizing that literal operators cannot have default arguments.
• Forgetting that user-defined literal suffixes cannot conflict with existing standard literal suffixes (e.g., 'f', 'L', 'ULL').
• Not being aware of the potential for issues when using literal operators in different aspects of software development for mobile or embedded platforms with specific resource constraints.
• Can literals be used in concept definitions?
• Not being aware of the potential for issues when using literal operators with different data compression algorithms.
• Does C++ guarantee string literal pooling?
• Assuming that identical string literals always reside at the same memory address.
• How do user-defined literals interact with implicit conversions?
• How do you specify a 'float' literal?
• 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.
