Simplify the following expressions.
Assume b is a variable of type boolean.

b == true

b == false

b != true

b != false

Solution

note:

==,!= are called relational operators.They tell relation between 2 things

boolean values can have only 2 values ,true or false where true means 1 and false means 0

! symbol means complemnent of a number.If true,then not of true becomes false i.e !(1)=0

or

  If false,then not of false becomes true i.e !(0)=1

b==true

this means if b value is true,then output will be 1,otherwise 0

b==false

this means if b value is false,then output will be 1,otherwise 0

b!=true

this means if b value is false,then output will be 1,otherwise 0

b!=false

this means if b value is true,then output will be 1,otherwise 0
