If you're looking to obtain Charizard, one of the most popular Pokemon in the history of the franchise, there is only one way to do so within Pokemon FireRed: Choose Charmander as your Starter Pokemon. Charmander will Evolve into Charmeleon at Level 16, and then Charmeleon will evolve into Charizard at Level 36.
Unfortunately, this is the only method to obtain Charizard within the structure of the game since neither Charizard or either of its Pre Evolutions can be found naturally in the Wild. Of course, Charizard is available by Trade should you connect with someone via the Wireless Adapter. You can even obtain Charizard via a cheat code with either an Action Replay Device or Code Breaker Device.
