変数Aが10を保持し、変数Bが20を保持すると仮定します-

Operator name	Operator simple	Description	Example
and	&&	Called Logical AND operator. If both the operands are non-zero then then condition becomes true.	(A && B) is true
or
Called Logical OR Operator. If any of the two operands is non-zero then then condition becomes true.	(A		B) is true
not	!	Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.	!(A && B) is false

例

void loop () {
   int a = 9,b = 4
   bool c = false;
   if((a > b)&& (b < a))
      c = true;
   else
      c = false;

   if((a == b)|| (b < a))
      c = true;
   else
      c = false;

   if( !(a == b)&& (b < a))
      c = true;
   else
      c = false;
}

結果

c = true
c = true
c = true
