C# - Logical and: &&

Logical and works as follows: just in case it's true if both inputs are true in all other situations the result is false. In next table you can find all possibilities:

a	b	x
False	False	False
False	True	False
True	False	False
True	True	True

information about the table: a, b are inputs, x is result

&&

Description

par1 && par2

Used keywords: &&

Input

par1 - Logical value
par2 - Logical value

Output

Result - Logical value

If the first operand is false, then the second operand is not evaluated.

Examples

C#

In the source code you can find the equivalent of the above table, for easier orientation at the end of each line is a comment which shows the result.

a1 = false && false; // a1 = false
a2 = false && true; // a2 = false
a3 = true && false; // a3 = false
a4 = true && true;  // a4 = true

C#

Even one example in what situations we can use the operation logical and:

a && b
a && true
10 >a && a>5

C#

Other pieces of example codes:

a && b

!b && true

 b2 = x && y
