Question

The rules that must be followed when constructing a program are called __________.

Short answer

Answer: The term is "syntax". Syntax defines the rules and structures for writing code in a programming language. Examples of syntax in Python and Java are as follows: Python example: ```python def add_numbers(x, y): return x + y result = add_numbers(2, 3) print(result) ``` Java example: ```java public class AddNumbers { public static void main(String[] args) { int x = 2; int y = 3; int result = addNumbers(x, y); System.out.println(result); } public static int addNumbers(int x, int y) { return x + y; } } ``` Each programming language has its unique syntax, as seen in the examples above.

Step-by-step solution

Identify the term

The term we're looking for is "syntax". Syntax refers to a set of rules and structures that dictate how to write code in a programming language.

Understand what syntax is in the context of programming languages

Syntax is the grammar, punctuation, and spelling of a programming language. It defines how the code should be written to be correctly understood and executed by a computer. Each programming language has its own unique syntax.

Give examples of syntax in different programming languages

Here are two examples for different programming languages, Python and Java, which demonstrate the syntax required for each: Python example: ```python def add_numbers(x, y): return x + y result = add_numbers(2, 3) print(result) ``` Java example: ```java public class AddNumbers { public static void main(String[] args) { int x = 2; int y = 3; int result = addNumbers(x, y); System.out.println(result); } public static int addNumbers(int x, int y) { return x + y; } } ``` As seen from the examples, each programming language has its own way of defining functions and displaying the output, which forms their unique syntax.
