A fluid cup (water, milk, chicken stock, etc.) holds 8 fluid oz of liquid.
A dry cup (flour, sugar, etc.) holds 16 tablespoons of solids
A cup is a VOLUME measure.
Be warned that it's easy with powders (flour, cornstarch) to overpack a cup and put a lot more flour in it than is expected. A cup of flour should weigh 120 grams. If you scoop the flour out of a bag, you could still fill the cup but it may have 200g of flour, almost twice what a recipe requires. If you sift first then spoon into your cup and level, you could get too light at 100g but at least you're likely more accurate even if not totally.
For dry ingredients, it's always most accurate to weigh them; and weight in grams is more accurate (and easy, it's all divided by 10's) than ounces (divided by 16's and 12's and 4's..).
Liquids are OK in your typical glass measuring cup since you can't overpack it.
