Boolean expression:

  • A Boolean expression is an expression that contains a sequence of identifiers separated using the operators that evaluates to Boolean variable, which means either true or false.
  • The Boolean expression is as follows:
  • Boolean variable
    • A Boolean variable is a variable or a data type which is placed in memory and referenced by an identifier.
    • Boolean variable contains two values “true” or “false”.
  • Relational operator
    • Relational operators are used to compare numeric and character values.
    • It has six relation operators which will compare two numbers and returns a Boolean value.
      • < (Less than)
      • > (Greater than)
      • <= (Less than or equal to)
      • >= (Greater than or equal to)
      • ! = or <> or /= (Not equal to)
      • = or == (equal)
        • The result of the comparison will be either “true” or “false”.
        • The Boolean value is hold by the variable called Boolean variable.
        • The data type “Boolean” is used to declare the Boolean data type.
  • Boolean operator
    • The Boolean operator is a special operator and subset of the Boolean algebra that produces the “true” or “false” statement.
    • The “AND”, “OR”, and “NOT” are the Boolean operators.

Explanation of Solution

b.

Given expression:

7<= (x + 2)

In the given question, “x” value is “5”, “y” is “6”, and “z” is “8”. Here, first the value of “x” is added with “2”, because bracket is evaluated first in the relational expression...

Explanation of Solution

c.

Given expression:

z< 4

In the given question, “x” value is “5”, “y” is “6”, and “z” is “8”...

Explanation of Solution

d.

Given expression:

(2 + x) <> y

In the given question, “x” value is “5”, “y” is “6”, and “z” is “8”. Here, first “2” is added with the value of “x”, because bracket is evaluated first in the relational expression...

Explanation of Solution

g.

Given expression:

X <= (y * 2)

In the given question, “x” value is “5”, “y” is “6”, and “z” is “8”. Here, first “y” value is multiplied with “2”, because bracket is evaluated first in the relational expression...
