Zero inflation means no price changes and that never happens in a free market. Prices always change when free people are allowed to charge what they want and pay what they want. The only way to have zero inflation is with an all powerful state run economy. Ah, my bad, zero inflation's also possible when everyone's dead.

Inflation is a rise in the general price level, caused by the government devaluing the currency.
