Question

Describe numerical, relational, and logical expressions. Include the type of operators each contains and the type of value (numerical or boolean) it produces when evaluated.

Answer 1

Numerical Expressions:Numerical operators are used on two operands then those expressions are called as Numerical expressions.

2+3=5 (+ operator it returns a numerical value)

5-3=2(- operator it returns a numerical value)

5*2=10(* operator it returns a numerical value)

10%2=0(% operator it returns a numerical value)

10/2=5 (/ operator it returns a numerical value)

Relational Expressions:Relational operators are used to compare two operands.These operator will returns TRUE or FALSE,if condition satisfy it will return TRUE otherwise it will returns FALSE

3>5(> greater than operator)

3<5(< lessthan operator)

5==5 (comparision operator)

3>=5(less than or equal operator)

3<=5(greater than or equal opearator)

3!=5(not equal operator)

Logical expressions:

&&-logical AND it returns TRUE if both conditions are TRUE

||-Logical OR it returns TRUE atleat one of the condition is TRUE

!-Logical NOT it reverse the operand state
