Blockly

An important criterion for assessing programming language is the ease with which programs can be read and understood.

Readability

In characteristics that contribute to the readability of a programming language, The overall simplicity of a programming language strongly impacts its readability. For example, a larger number of basic constructs in a language is more difficult to learn than one with a smaller number.

Simplicity

"a scenario of more than one (1) way to accomplish a particular operation." Identify what problems in readability is in the given statement.

Feature Multiplicity

"a scenario wherein a single operator symbol has more than one (1) meaning. It can result in reduced readability if users create their overloading and do not do it sensibly." Identify what problems in readability is in the given statement.

Operator Overloading

"a scenario wherein the language is too simple to the point of lacking more complex statements and less obvious program structure." Identify what problems in readability is in the given statement.

Oversimplicity

It is the ability to change one thing without unseen effects on other things in the program.

Orthogonality

which statement is NOT TRUE about Orthogonality?

The presence of adequate facilities for defining data types and data structure offers a significant aid to readability.

The presence of adequate facilities for defining data types and data structure offers a significant aid to readability. For instance, it might not be easily understood if a numeric type is used for an indicator flag, such as in C language, because there is no Boolean type in the language.

Data Types

The syntax or form of the elements has an impact on the readability of programs.

Syntax Design

Some programming languages have used matching pairs of special words or symbols to form groups. These languages have diminished readability as statement groups are always terminated in the same way, making it difficult to determine which group is being ended when an end or a right brace appears ( } ).

Special Words

Designing statements to make their appearance partially specify their purpose, which helps readability. Semantics, or meaning, must follow directly from syntax or form.

Form and Meaning

It is the measure of how easily a language can be used to create programs for a chosen problem domain. It is unfair to compare the writability of different languages of a particular application when one is designed for that application and one that was not.

Writability

A large number of different constructs in a language might confuse some programmers as they might not be familiar with them. This leads to the misuse and disuse of some features.

Simplicity and Orthogonality

Which statement is NOT TRUE about Simplicity and Orthogonality in Writability?

This refers to various characteristics.

It is in a language refers to various characteristics. It means that there are more effective operators that allow a computation to be accomplished with a very small program.

Expressivity

Which statement is NOT TRUE about Expressivity in Writability?

A large number of different constructs in a language might confuse some programmers as they might not be familiar with them. This leads to the misuse and disuse of some features.

It is met if a program performs to its specifications under all conditions.

Reliability

It tests for the type of errors in a program, either by the compiler or during program execution.

Type Checking

Which statement is NOT TRUE about Type Checking?

It is the ability of the program to intercept runtime errors and other unusual conditions detectable by the program, take corrective measures, and then continue.

It is the ability of the program to intercept runtime errors and other unusual conditions detectable by the program, take corrective measures, and then continue

Exception Handling

It happens when there are two (2) or more distinct names in a program that can be used to access the same memory cell. It is considered and accepted as a dangerous feature in a programming language.

Aliasing

A language that does not support natural ways to express the required algorithms in a program will use unnatural approaches that are likely to be incorrect for all possible situations. A program is more likely to be correct if it is easier to write. Additionally, a program that is difficult to read can also be difficult to write and modify.

Readability and Writability

Studying programming languages can be divided into examinations of ___________?

syntax and semantics

It is the form of its expressions, statements, and program units. It defines the meaning of the various combinations of symbols used in programming and describes which strings of characters comprise a valid program

Syntax

It is a program written in a high-level programming language

Source Code

This is the file containing the source code

Source File

These reserved words that have a special meaning in the language. They form the basic building blocks for writing programs. Examples include if, else, for, and while.

Keywords

These are symbols that perform operations on variables and values. Examples include arithmetic operators like + and -and logical operators like && and ||.

Operators

It includes symbols such as commas, semicolons, and braces that help structure the program. They indicate the end of statements or encapsulate blocks of code

Punctuation

These are names that identify user-defined items such as variables, functions, and arrays.

Identifiers

It is a natural notation for describing syntax.

BNF (Backus-Naur Form)

Which statement is NOT TRUE about BNF Notation?

it is a tree representation of the syntactic structure of the source code.

Who were the people that developed BNF Notation?

John Backus and Peter Naur

It is a language or set of terms used to describe another language.

Metalanguage

It can be created by combining terminals and nonterminals. These also called production rules

BNF rules

It is a set of BNF rules

BNF grammar

In BNF Notation, These are strings that must exactly match specific items in the input

Terminals

In BNF Notation, These are symbols that will be replaced by a concrete value.

Nonterminals

In BNF Notation, These are conventions of terminals and nonterminals that defined how the elements relate.

Rules

It is a tree representation of the syntactic structure of the source code.

Abstract Syntax Tree (AST),

Which statement is NOT TRUE about Abstract Syntax Tree?

It is the meaning of those expressions, statements, and program units that syntax forms.

Semantics

It involves rules checked simultaneously, such as type checking and scope resolution. These rules ensure that certain errors are caught before the program runs, enhancing reliability and robustness. For instance, if a variable is used without being declared, a statically typed language will flag an error before execution.

Static semantics

Which statement is NOT TRUE about Static Semantics

It refers to the behavior of a program when it is run.

It refers to the behavior of a program when it is run. It includes the execution of expressions, control structures like loops and conditionals, and manipulating data through functions and procedures.

Dynamic semantics

Which statement is NOT TRUE about Dynamic semantics

It involves rules checked simultaneously, such as type checking and scope resolution.

It describes the behavior of a program in terms of abstract machine execution steps. For instance, it outlines how each expression or statement is evaluated step-by-step, making it ideal for simulating program execution.

Operational Semantics

It maps syntactic constructs to mathematical objects, offering an abstract, mathematical description of their meaning. This approach helps in reasoning about program correctness and equivalence. For example, a function in programming might be represented as a mathematical mapping between input and output values.

Denotational Semantics

It uses logical assertions, such as preconditions and postconditions, to specify and prove properties about a program. It is especially useful in verifying the correctness of algorithms.
