Question

True or False A conditionally executed statement should be indented one level from the if statement.

Short answer

Answer: True

Step-by-step solution

Understanding Conditional Statements

Conditional statements are a fundamental concept in programming. They allow a program to perform different actions based on specified conditions. In most programming languages, conditional statements are created using keyword `if`, followed by a condition in parentheses and a block of code to be executed if the condition is met. For example, in Python: ```python if age >= 18: print("You are an adult.") ```

Step 2:Understanding Indentation

Indentation is the practice of using spaces or tabs at the beginning of a line to indicate the level of nesting (or the current position of the code block within the structure of the code). Different programming languages have their syntax rules with regards to indentation. In Python, for instance, indentation is used to define the structure of the code and is required by the language. Each level of indentation typically consists of 4 spaces or a tab.

Analyzing the Relationship Between Conditional Statements and Indentation

In Python and many other programming languages, indenting is specifically used to separate blocks of code. This separation makes it easy to tell which parts of the code are governed by a specific conditional statement. When using conditional statements, the block of code that is executed only if the condition is true (conditional block) should be indented one level from the `if` statement. This indentation signals that the statements within the indented block are a direct consequence of the preceding `if` condition being met. Here's an example in Python: ```python if age >= 18: print("You are an adult.") # indented one level from the if statement ``` The `print` statement is indented one level from the `if` statement because it is conditionally executed — it will only execute if the `age` is greater or equal to 18.

Answering the Exercise

With the understanding of both conditional statements and indentation, we can now answer the given exercise. The statement "A conditionally executed statement should be indented one level from the `if` statement" is: True
