FreeBASIC - Logical and: and, AndAlso

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

and

Description

par1 and par2

Used keywords: and

Input

par1 - Logical value
par2 - Logical value

Output

Result - Logical value

Both operands are evaluated independently of the value of the first operand.

Examples

FreeBASIC

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 and false ' a1 = false
a2 = false and true ' a2 = false
a3 = true and false ' a3 = false
a4 = true and true  ' a4 = true

FreeBASIC

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

a and b
a and true
10 >a and a>5

FreeBASIC

Other pieces of example codes:

a and b

not b and true

Dim b2 As boolean= x and y

AndAlso

Description

par1 AndAlso par2

Used keywords: andalso

Input

par1 - Logical value
par2 - Logical value

Output

Result - Logical value

The second operand is evaluated only in the case when the value of the first operand is true.

Examples

FreeBASIC

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 AndAlso false ' a1 = false
a2 = false AndAlso true ' a2 = false
a3 = true AndAlso false ' a3 = false
a4 = true AndAlso true  ' a4 = true

FreeBASIC

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

a and b
a and true
10 >a and a>5

You can find it in the following collections: logical operators
