Conditional and logical operators

Operator	Type	Description
>	Conditional	Evaluates whether the value on the left is greater than the value on the right
<	Conditional	Evaluates whether the value on the right is grater than the value on the left
>=, <=	Conditional	Evaluates the same as > or < bur with the additional logic that the values can also be equal
!=	Conditional	Evaluates whether the values aren't equal
==	Conditional	Evaluates whether the values are qual independent of the underlying data type
===	Conditional	Evaluates whether the values are equal both in value and underlying data type
&&	Logical	The AND logical operator, in which the expressions on both sides must evaluate to true
\|\|	Logical	The OR logical operator, in which at least one expression on either side must evaluate to true

We will use logical operators to combine conditional operators.

Example:

if(age >= 12)
{
    if(age <= 65)
    {
        // logic goes here
    }
}

In the above example first age >= 12 will be evaluated, if it is true then only age <= 65 is evaluated. So, we can combine these two statements into one statement by using Logical operators.

if(age >= 12 && age <= 65)
{
    // logic goes here
}
