i need to know which IC's should i use to display the temperature in 7-segment display.. i am using lm35 and adc0804 what should i do next??

Change your mind and use a microcontroller - it would be much easier

the project requirement is to contstruct it without micro controller.

If this is a project requirement then surely its purpose is to test your knowledge and ingenuity. It's not likely to achieve its aim if someone does the project for you.

Hi obaid123,
You could use a ICL7107 details are here:

It has an A/D which can convert voltage from your LM35 and digitize it to display on the LED. All you need would be a scaling circuit in between which would typically be an opamp amplifier.

This should be enough hints for you to do it on your own.
