Question
What is the default value of boolean?
Options: Pick one correct answer from below
- true
- false
Solution
The default value of a boolean in most programming languages is false
.
This means that if you declare a boolean variable without explicitly initializing it, it will automatically take on the value of false
. This is important to understand, as relying on a default value can lead to logic errors in your code if you assume a boolean starts as true
.
For example, in Java and C#, when a boolean is declared as a class member or instance variable, it defaults to false
. However, local boolean variables (those declared inside a method) must be explicitly initialized before use; otherwise, the compiler will throw an error.
In summary, understanding default values is crucial for effective programming and avoiding unintended behaviors in logic. Always make sure to initialize variables as required by your specific programming context.
Final Answer
The default value of boolean is false.
