As a sentence ender: Jane and Jack went to the market.
After an abbreviation: Her son, John Jones Jr., was born on Dec. 6, 2008.
Use a question mark (?) to indicate a direct question when placed at the end of a sentence.
When did Jane leave for the market?
The exclamation point (!) is used when a person wants to express a sudden outcry or add emphasis.
Within dialogue: "Holy cow!" screamed Jane.
To emphasize a point: My mother-in-law's rants make me [furious][][[][][[[][]][!.
