Check my tutorials, which contain everything you need to do it - although you will have to use bits from various tutorials.

thanks but that was bit harder for me,cause m a new comer in feild of programming ,ur tutorial contains this type of programming using interrupts.i tried doing in a better and simpler way without using interrupts.

The interrupts make it easier! - it makes the multiplexing completely transparent to your main program. If you don't want to use interrupts you have the problem of maintaining reasonably accurate multiplexing whilst checking the keys, de-bouncing, and everything else!.
