A basic digital camera cost in the range of 80.00 to 120.00.  A beginner should stay in this price range.  Extra accessories  increase the price.  When checking out cameras try to get the most onboard memory called megapixels.  The more megapixels the better picture quality.
     When using a digital camera indoors,  its basically the same as cameras with film.  That is, you need a digital camera with a flash.   And the same basic rules apply to taking pictures indoors.  You must be 5 to 10 feet away from your subject for the FLASH to do its job.
     BATTERIES.   Try purchasing a camera that uses standard alkaline AA batteries.  Some cameras use only 2 batteries  but some models may use 6 batteries.  Stay with double AA batteries to keep your operating costs down.  Usually the more accessories on the camera will require more power ,, such as zoom.
     A  basic digital camera without a zoom feature will usually take a picture at a 50 mm setting which is the most compatible to the way the human eye sees things.  Without zoom the camera will have around a 50 mm lens with infinite focus.  I recommend you stay away from purchasing this type of camera.   Buy one with some zoom,  you'll be looking for a little zoom lens capability.
    Several ways to look at the pictures you take.  A small screen on the back of the camera allows you to view your photos and also its used as a view finder to take your photos.  I would purchase a digital camera that has both options, that is,  a regular viewfinder and a miniscreen viewfinder.
Purchase one with a color view finder.    I dont know your age or if you use bifocals but try to get the largest miniscreen viewfinder.  Try to get one in the 3 inch or more range and color.   But most miniscreen viewfinders are hard to see outside in the sun,,, that is why also have the regular viewfinder on the camera.   Some miniscreen viewfinders can be seen in bright sunlight ,, but you have to adjust the settings and all of this will have an increase battery drain.  (carry spare batteries with you)
   I dont recommend you purchase a camera with printing your own pictures in mind.   The paper is expensive and the ink is also expensive.   This comes to the subject of how and where your pictures are stored on the camera.   Most cameras can store pictures on its internal memory but it usually gets used up fast.   Most cameras have a removable memory card that can be inserted into your computer and you can view your pictures there.    BUT I recommend taking your pictures onto the removable memory and taking this memory card to WAL MART and or KMART, SAMS CLub etc.   Near their photo departments they have a place where you can print your own pictures from your memory card.  Its costs a couple of pennies per picture but its worth it.
    And that comes to where to buy the camera.    You should buy it at WALMART or KMART.  And save your sales receipt.   Use the camera to see if your satisfied with it.   If you are not ,,, take it back and exchange it.    Its easier to exchange at WALMART and KMART.   Try a few and return a few.
You'll find the one you like that's best suited for your needs.
 
Oh and dont point it at the sun.
 
 
Good Luck
