Prince Charles is officially styled as follows (warning: it's quite the mouthful):
His Royal Highness The Prince Charles Philip Arthur George, Prince of Wales and Earl of Chester, Duke of Cornwall, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles, Prince and Great Steward of Scotland, Royal Knight Companion of the Most Noble Order of the Garter, Royal Knight Companion of the Most Ancient and Most Noble Order of the Thistle, Knight Grand Cross of the Most Honourable Order of the Bath, Member of the Order of Merit, Knight of the Order of Australia, Companion of the Queen's Service Order, Member of Her Majesty's Most Honourable Privy Council, Aide-de-Camp to Her Majesty
In English, this means he is the heir to the throne of England (Prince of Wales) and Scotland (Duke of Rothesay) as well as a Duke of the United Kingdom (Duke of Cornwall). He holds several subservient titles (Earl of Chester and Carrick, Baron of Renfrew, etc) some of which will likely be passed on to Prince Harry when he marries. Also listed are his numerous knighthoods and his position as Aide-de-Camp to Her Majesty the Queen (making him second-in-command of the British Armed Forces). He has numerous other (and smaller) titles and honors, but they are never used unless the occasion specifically calls for it (for example, the Grand Duke of Luxembourg made him a Knight Grand Cross of the Order of the Oak Crown, Luxembourg's premier knighthood, but unless the Prince is visiting Luxembourg he would not use that title).
His wife, Princess Camilla, is officially styled as follows:
Her Royal Highness The Princess Charles Philip Arthur George, Duchess of Cornwall, Duchess of Rothesay, Countess of Carrick, Baroness of Renfrew, Lady of the Isles, Princess of Scotland, Dame Grand Cross of the Royal Victorian Order
You'll notice that Camilla shares many of Charles' titles, including being officially referred to as "Princess Charles" (similarly to how many married women - although usually of an earlier time - were legally "Mrs. John Doe" instead of "Mrs. Jane Doe;" they took on their husband's full name and added "Mrs." to the front). Camilla has fewer titles because she has been a Princess, and therefore a public servant, for less time - she has not had time to accrue as many honors as her husband.
Prince Charles will one day succeed his mother as Sovereign Monarch of the United Kingdom. When he does, he shall take a 'regnal name' which may or may not be "Charles." It is speculated, indeed, that he will choose "George" in honor of his grandfather George VI and to disassociate himself from the unpopular Stuart monarchs (Charles I and Charles II). If he chooses "George," he will become His Royal Majesty King George VII of the United Kingdom of Great Britain and Northern Ireland and the Commonwealth Realms. He will also have a seemingly unending stream of other titles and honors, both British and foreign, thrust upon him. Camilla will either become Her Royal Majesty Queen Camilla, Queen-Consort of the United Kingdom etc, or she may choose to become Her Royal Highness Princess Camilla, the Princess-Consort, in a tribute to the Lady Diana, the former Princess of Wales, who died tragically in 1996 before she could become Queen-Consort.
And lastly, if you read nothing else please read this: while Prince Charles and Princess Camilla hold all the titles, styles, and honors as listed above, they typically are referred to by the following ways:
HRH Prince Charles
or
HRH The Prince of Wales
or
HRH The Duke of Cornwall and Rothesay
HRH Princess Camilla,
or
HRH The Princess of Wales
or
HRH The Duchess of Cornwall
If you ever meet either of Their Royal Highnesses, they are to be addressed as "Your Royal Highness" or "Your Highness" upon first introduction and then "Sir" or "Ma'am" (as appropriate) every time you wish to address them afterwards.
