In the given syntax, “x” and “y” are the operands on which the && operator will be applied.
Truth Table of && Operator
|x||y||x && y|
The “AND(&&)” operator has comparatively higher precedence than the “OR(||)” operator in such a way that the && operator is executed before the || operator.
The following example explains the precedence concept.
In this example, the statement (true && false) will execute first due to the higher precedence of the “AND(&&)” operator. This will result in “false”:
Now, the statement becomes:
The “OR” of both the false statements will yield:
Example 1: Applying AND(&&) Operator on the Boolean Values
In the following example, we will first assign “true” as boolean values to both variables named “x” and “y”. Then, apply the “&&” operator. As both of the values are true, so the resultant value will be true:
Similarly, assign the following boolean values to the same variables and apply the “&&” operator. This will result in “false” as one value is false:
Likewise, analyze the following conditions based on the discussed concept of “&&” operator and log the corresponding boolean value:
The corresponding output will be:
In the above output, it is evident that only the first value is true which is a result of both the operands being true.
Example 2: Applying AND(&&) Operator on the Initialized Value
In this example, initialize a value “1” to the following variable:
Next, apply the “&&” operator with the following values to the initialized value and observe the result:
It can be seen that logical AND “&&=” operation is successfully applied in the both statement which updated the value of the x variable likewise:
Example 3: Applying AND(&&) Operator as a Condition
Firstly, ask the user to input a value via prompt:
Now, if the entered value satisfies both of the following conditions using “&&” operator, the “if” block will execute:
In the other case, the below “else” block will execute:
