Question

What is the purpose of boolean in branching statements?

1) To control the flow of execution based on a condition
2) To declare variables
3) To perform mathematical operations
4) To print output

Answer 1

Boolean in branching statements is used to control program execution based on conditions using Boolean expressions and operators like AND, OR, and NOT.

Step-by-step explanation:

The purpose of Boolean in branching statements is to control the flow of execution based on a condition. When writing computer programs, especially in high-level languages, Boolean expressions are fundamental in making decisions. Branching statements like if, while, and switch rely on Boolean expressions to determine which path of code to follow. For example, an if statement will execute a block of code only if a Boolean condition evaluates to true. Boolean expressions employ Boolean operators such as AND, OR, and NOT to combine or exclude conditions, which helps in making more complex decision structures.

For instance, if a search involves finding a specific article by an author named Buiten from the year 2019, the Boolean expression would be "title" AND "Buiten" AND "2019". This expression would include all items that have the specified title, are written by Buiten, and are published in the year 2019. The powerful control afforded by Boolean logic is essential in programming and also in various problem-solving contexts like database searches or mathematical modeling.
