Which of the following statements is true?,

• Learning Objectives:

Understand binding and typing and namespaces  

• A binding is an association between an entity and an attribute, such as between a variable and its type or value, or between an operation and a symbol

Understand variable scope  Be able to identify both static and dynamic scope

• Variablescope is the range of statements in which the variable is visible

• A variable is visible in a statement if it can be referenced or assigned in that statement

• Static scoping is when the scope of a variable is determined prior to program execution and is unchanged throughout (can be located prior to execution) 

• Dynamic scoping is when the scope is determined at run time and can change during execution

Understand basic types and their implementation

• The type  of a variable determines the range of values the variable can store and the set of operations that are defined for values of the type

• Types tell the compiler and the CPU how to interpret the ones and zeros in memory

• The type dictates how much memory to allocate and specifies how data should be interpreted

Know implementation of arrays

• row-major order and column-major order are methods for storing multidimensional arrays in linear storage such as random access memory.

Be able to program and/or trace simple FORTRAN, Python, C
