Statement I is true, as it is a common convention to name constants using uppercase letters to distinguish them from variables. However, it is not a requirement.
Statement II is false, as constants can have various data types, including integers, floating-point numbers, and strings.

Statement IV is true, as using named constants in computations can make the code more readable and understandable.
