Most stores will let you handle a number of cameras to help you get a feel for how easy or difficult each is to use. Some cameras have easy to find and use features while others hide even the necessary functions under layers of menus. Perhaps a few minutes looking at the basics will help. Since the X-Y axis used to describe resolution is pretty much the same for any camera many manufacturers simply multiply the two numbers and refer to resolution in megapixels. As a rule of thumb a 640x480 pixel file is more than enough for a video or computer screen and can be used to produce an acceptable 3x5 in.
Some cameras offer digitally enhanced resolution to simulate more pixels.
However, the result is not the same as shooting at higher resolution. If you have a film camera that you're comfortable with, look for a digital camera with similar features. Select an inexpensive, easy to use camera and start tormenting every one. Printers are being designed now for just this purpose. Some cameras even use standard or high capacity floppy discs for storage.
