Responding to: ???'s previous message
Then it's time for you to get onto a training course, and/or sit down with a few good textbooks, and start learning!

when i press 1st push button 1st seven segment start blinking after it increament/decreament by 2nd/3rd push button in 1st seven segment .
again when i press 1st push button 2nd seven segment start blinking after it increament/decreament by 2nd/3rd push button in 2nd seven segment .
again when i press 1st push button 3rd seven segment start blinking after it increament/decreament by 2nd/3rd push button in 3rd seven segment
again when i press 1st push button 4th seven segment start blinking after it increament/decreament by 2nd/3rd push button in 4th seven segment.


None of this has anything to do with switch interfacing - it's about software design.

Hint: try googling "State Machine" or "Finite State Machine" or "FSM"...

plz try to help me

A bit of "Help" is one thing; a complete course in programming is quite another!
