Saving multiple texts to an array

I have writtern this code to ask user to input number of rooms(x) (integer),room area (area(i)) (integer) and room type (string) and based on these selections, Q_env is calculated

This the code

to=input('Enter outside temperature: ');
ti=input('Enter inside temperature: ');
x=input('No of room: ');
for i=1:x
    fprintf('ROOM %4.0f:', i)
    area(i)=input('Area in meter square = ');
    rt=input('Room type: ','s');    
end

   if   rt=="external"
        u1=0.6993;
        dt=abs(to-ti);
        Q_env=u1*area*dt
        else if rt=="internal"
        u2=1.3858;
        dt=abs(to-ti);
        Q_env=u2*area*dt
            end
   end

The following results are displayed when I run the previous code

Enter outside temperature: 40

Enter inside temperature: 20

No of room: 2

ROOM 1:Area in meter square = 20

Room type: internal

ROOM 2:Area in meter square = 30

Room type: external

Q_env =

279.7200

419.5800

419.5800

There are two problems here:

1. rt only saves the last user input and I need all the room types corresponding to each room area to be saved to an array.

1. Q_env is diplayed for the given number of rooms and the last result is repeated.

How can I overcome these two issues?

You have solved storing the set of areas using: area(i) . To store the set of CHAR vectors in a cell array, use: rt{i} .

If you do not want to display the resulat of a command, append a semicolon:

Q_env = u1 * area * dt;
%                     ^
