I have made a loop to go through each floor and ask the number of residential spaces on that floor then plot it. I now need to work out the total number of residential spaces (all floors considered) but I am not sure how to go about this.

for c = 1:1:sBuilding(n).bNoOfFloors
    disp("--------------FLOOR "+c+" --------------")
    subplot(sBuilding(n).bNoOfFloors,1,c);
    title(sprintf('Floor %d',c));
    sFloor(c).NoOfResidentialSpaces = input('Enter Number Of Residential spaces:');
    if sFloor(c).NoOfResidentialSpaces > 0
        for i = 1:1:sFloor(c).NoOfResidentialSpaces
            sFloor(c).resident(i).width = input("Enter width of Residential room " +i+" on floor "+c+":");
            sFloor(c).resident(i).length = input("Enter length of Residential room "+i+" on floor "+c+":");
            choice1 = questdlg('Would you like to draw a floorplan?','question','yes','no','yes');
            switch choice1
                case 'no'  
                    disp('No floorplan')
                case 'yes'
                    locationx=input("Please specify bottom left corner X coordinate of residential room "+i+" on floor "+c+":");
                    locationy=input("Please specify bottom left corner Y coordinate of residential room "+i+" on floor "+c+":");
                    rectangle('Position',[locationx locationy sFloor(c).resident(i).width sFloor(c).resident(i).length]);
                    axis ([0 100 0 100]);
                    hold on
            end
        end
    end
end

You could create a sum as you loop through:

roomtotal = 0;
for c = 1:1:sBuilding(n).bNoOfFloors
    disp("--------------FLOOR "+c+" --------------")
    subplot(sBuilding(n).bNoOfFloors,1,c);
    title(sprintf('Floor %d',c));
    floortotal = input('Enter Number Of Residential spaces:');
    sFloor(c).NoOfResidentialSpaces = floortotal;
    roomtotal = roomtotal + floortotal;
    if sFloor(c).NoOfResidentialSpaces > 0
        for i = 1:1:sFloor(c).NoOfResidentialSpaces
