Which is true of stacking structures? Each structure has only one point where it can be stacked on top of another. Two incidences of the same structure cannot be stacked adjacently. When you stack structures, you cannot nest them in the same program. When you stack structures, the top structure must be a sequence.

A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1.

- Direction Fields Plotting Direction fields can be done using the function quiver: quiver Quiver plot. quiver (X,Y.U.V) plots velocity vectors as arrows with components (u.v) at the points (x,y). The matrices X,Y,U,V must all be the same size and contain corresponding position and velocity components (X and Y can also be vectors to specify a uniform grid). quiver automatically scales the arrows to fit within the grid. Example: xrange = -5:0.5:5; %the domain of x is from -5 up to 5 with 0.5 interval. yrange= -10:1:10; %the values of y is from -10 up to 10 with 1 interval.
