Study Notes
Programming Language Design Issues
- Design issues for names include considerations such as readability, scope, and naming conventions which can impact programming efficiency and maintainability.
Limit on Length of Names
- COBOL imposes a specific limit on the length of external names, influencing how developers structure their identifiers.
Requirement of Special Characters
- In PL/1, all variable names must start with special characters that indicate the variable’s type, enforcing a strict naming convention that aids in type identification.
Mixed Case Predefined Names
- In some programming languages, such as C and C++, predefined names use mixed case which may lead to inconsistency and hinder readability for programmers.
Variables in Imperative Languages
- Variables in imperative languages are characterized by attributes such as scope, lifetime, and type, each playing a crucial role in how variables operate within the code context.
