An american cup generally holds 90-110g of flour, dependant on the type. I know that it's around 100g of all-purpose (plain) flour.
I use this recipe for most of my breadmaking, it's quick, versatile and cheap:
500g of strong bread flour 7g sachet of dried yeast 3 tablespoons of oil 300ml of warm water 1 tsp salt 1/2 tsp sugar
Mix flour, yeast, salt and sugar together in a large bowl. Make a well, add warm water and oil, mix with a butterknife until dough is formed. I don't use a breadmaker, but from here you'd let the breadmaker take over I assume
We had one for years, then upgraded to a fancier One of a different make. I have always used the same bread recipe in it. Actually I think I still have my Hinari recipe booklet which I could probably copy for you easily.
My bread machine recipe is: 275 ml water 450g bread flour 1 tsp salt 1 tsp sugar 1 tsp yeast for bread machines 25g butter 1 tbsp dried milk powder
Put them all in in that order and away you go.
You can then add all sorts. For a breakfast loaf I add 100g raisins and2 tsp cinnamon or for a savoury loaf some grated cheese. All lovely!
