Expert Solution & Answer
Chapter 2, Problem 14PS
Explanation of Solution
Typeless languages:
Typeless languages are referred to those languages which does not require any explicit type declarations.
Arguments for the idea of typeless language:
- Flexibility and easiness in use.
- Any variable can be used as any data type.
- Any storage location can be used for any data value. This is extremely useful in low level language used for system
programming . - The programmer is free to develop code quickly without much thought about defining variables using in the program...
