Hi guys just wondering if i connect the outputs of a single cd4026be decade counter ic to a,b,c etc on a 4 digit 7 segment display could i drive it using an arduino providing the clock pulse? thanks in advance

Yes, but study the data sheet carefully. You need current limiting resistors on each segment, and the proper common anode or cathode arrangement. There are better choices.

so what is the best option for this application (i have managed to have the cd4026 drive a single digit display)

Why that chip? A max7219 is a much better choice.

but it thought that as i only need to count up and reset that a more barebones chip woukld be more costeffective

I wouldn't connect that chip directly, You'd need to add some MOSFET or BJT and some diodes, which would kill any savings. Are you planning on using this with an Arduino? If so then the max7219 is one of the best ways to go.

yeah im using arduino. so ill look into max7219

For about the same cost as an individual chip, you can get a complete 4x 7-segment backpack, that is ready to be hooked up to your Arduino.

Can i drive 4 digit seven segment display with one cd4026be decade counter ic?

No worries
There are loads of examples on how to use them as well.
There are also 14-segment LEDs that let you do letters and numbers.
Have fun exploring!
