Question

Evaluate the following expressions and state the type of each expression:

int a = 2;
int b = 3;
double c = 3.0;

1. b / 2.0

Type: ( double, boolean, decimal, int )?

Value: ( answer )?

2. b ! = 3

Type: ( double, boolean, decimal, int )?

Value: ( answer )?

3. a >= 2.0

Type: ( boolean, double, char, int )?

Value: ( answer )?

Answer 1

1 -->

b is an integer datatype and value 2.0 is float/double.

when we divide an integer with a flaot, we get answer in float/double.

so, b / 2.0 type will be -> double.

now, when we divide 3 by 2.0 we get 1.5.

Type -> double , Value -> 1.5

2-->

b != 3

this is checking if b is not equal to 3. It is comparing, so its type will be boolean.

now, we have value of b = 3, so,

b != 3 is not true, hence it will give value as 0 (false)

Type -> Boolean , Value -> 0

3-->

a >= 2.0

this is also checking if a is greater or equal to 2.0, so its type will be boolean.

now, we have value of a = 2, so,

a>=2.0 is true, hence it will give value as 1 (True)

Type -> Boolean, Value -> 1
