Explanation / Answer

Hi,

Ans 1 - The return type of this function is integer.

Ans 2- The expression will result in 44
Steps-
=4*(3+8)
=4*11
=44

Ans 3- The argument belongs to "string" class.

Ans 4- True
This is because string can hold the negative sign it can strore the numbers in the form of string too.

Ans 5- The answer is 4
This is because the modulus operator returns the remainder of the two operands. In this case if we divide 4 by 8, we get 4 as remainder.

Ans 6- The answer is 0
This is because because the divide operator returns the quotient of the two operands. In this case if we divide 4 by 8, we get 0 as result.

Ans 7-This is an invalid function call. This is because the datatype of the parameter of this function is string.We are passing integer in the argument of the function which is incorrect.

Ans 8- The answer is -48
=)(4-8)*(4+8)
=)(-4)*(12)
=)-48

Ans 9- The output is 0
This is because the modulus operator returns the remainder of the two operands. In this case if we divide 8 by 4, we get 0 as remainder.
