I think you are doing mistake in second last line where you are trying to multiply size with 1 and then performing subtraction.. Why you intend to do this.. I mean subtracting value from address is not acceptable.. You have p as address now - 1 means if you are on address 1008 then downgrade to address 1000 assuming address size is 8..

i think mistake in second last line is that 1*sizeofchar should be there instead of 1*sizeofint and rest is ok

Check this out.. I hope you will understand what I was trying to make you understand..
