In programming languages, what is the primary advantage of strong typing?

Detection of type errors during compilation

How does dynamic scoping (DS) differ from static scoping (SS)?

SS is based on program text. DS is based on calling sequences.

The local and active subprogram variables

What is the purpose of type checking in programming languages?

To ensure that operands of operators have compatible types

What is the purpose of named constants in programming languages?

To simplify the use of literal values

What is the scope of a variable in a programming language?
