Which property cannot be modified once global constants and variables are created?

• A. Value
• B. Data Type
• C. Name
• D. All of the above

Answer: (D)

The property that cannot be modified once global constants and variables are created is indeed all of the mentioned options. When global constants are defined in a programming context, their value is set and remains unchanged throughout the lifecycle of the application. This immutability ensures that the constants serve their purpose of representing fixed values without the risk of unintentional modifications. Additionally, the data type of a constant or variable is established upon its creation. Once defined, changing the data type would require recreating the constant or variable, as the underlying representation of the value and its operations are tied to its initial type. Similarly, the name of a constant or variable is a fundamental characteristic assigned at the time of creation. It serves as the identifier for the constant or variable throughout the code; hence, renaming it would effectively involve creating a new entity. Together, these properties define the characteristics of constants and variables, solidifying their roles and ensuring consistency within the coding environment. This reinforces the principle that constants, in particular, are meant to be stable and unchanging elements within the software.
