1) f is 2.0 and 'G'+2 is 73. we get f as 2.0 though it was 5 divided by 2 because the operands were integer and hence we get 2.0 as output. if we defined 5 and 2 as floating point we could've got 2.5. In java, a char occupies 16 bit in UTF-16 encoding.G's unicode is U+0047, in binary 0000 0000 0100 1111.When you sum a char and an int(32 bit), the char will be promoted to int by inserting 0 into the begin of its binary representation. So 0000 0000 0100 1111 is converted to 0000 0000 0000 0000 0000 0000 0100 1111(in decimal, 71).That's why you get 73.
2) x is 4 as it gets pre decremented first then gets post incremented hence it remains as 4. y is 1 as it gets post decremented , Z is false as both are false statements and hence since its boolean operation of OR it results in false.
3)The outputs are:
one
two
three
four
five
2(result is 2 as per the operation performed from functions one(), two(), three(), four(), five())
