how to Align values

%price of each
TV_price = 20000.00;
LAPTOP_price = 40000.00;
SPEAKER_price = 6000.00;
MOUSE_price = 1000.00;
KEYBOARD_price = 3000.00;

%get input from user
TV = input('How many TVs were sold? ');
LAPTOP = input('How many Laptops were sold? ');
SPEAKER = input('How many Speakers were sold? ');
MOUSE = input('How many Computer Mouse were sold? ');
KEYBOARD = input('How many Keyboards were sold? ');
fprintf("\n-----------------------------------------------------\n");

%print bill
%Display
fprintf("\nQTY\tDESCRIPTION\t\tUNIT PRICE\tTOTAL PRICE\n");
fprintf("\n---\t-----------\t\t---------\t---------\n");

Read about table; this would be a nice way to present values.

Hi May Tanedo,

You could use “table” for presenting the values in an ordered way.

T = table([TV; LAPTOP; SPEAKER; MOUSE; KEYBOARD], ...
          ["TV"; "LAPTOP"; "SPEAKER"; "MOUSE"; "KEYBOARD"], ...
          [TV_price; LAPTOP_price; SPEAKER_price; MOUSE_price; KEYBOARD_price], ...
          [TV_total; LAPTOP_total; SPEAKER_total; MOUSE_total; KEYBOARD_total], ...
          'VariableNames', {'QTY', 'DESCRIPTION', 'UNIT_PRICE', 'TOTAL_PRICE'});

If you are not considering to convert the data, use format specifiers instead.

%3d and %10.2f are used for alignment, where the number specifies the minimum width of the field.

%-15s is used to left-align the description with a width of 15 characters.

fprintf("\n%-3s %-15s %-10s %-12s\n", "QTY", "DESCRIPTION", "UNIT PRICE", "TOTAL PRICE");
fprintf("%-3s %-15s %-10s %-12s\n", "---", "-----------", "---------", "-----------");

fprintf("%-3d %-15s %10.2f %12.2f\n", TV, "TV", TV_price, TV * TV_price);
fprintf("%-3d %-15s %10.2f %12.2f\n", LAPTOP, "LAPTOP", LAPTOP_price, LAPTOP * LAPTOP_price);
fprintf("%-3d %-15s %10.2f %12.2f\n", SPEAKER, "SPEAKER", SPEAKER_price, SPEAKER * SPEAKER_price);
fprintf("%-3d %-15s %10.2f %12.2f\n", MOUSE, "MOUSE", MOUSE_price, MOUSE * MOUSE_price);
fprintf("%-3d %-15s %10.2f %12.2f\n", KEYBOARD, "KEYBOARD", KEYBOARD_price, KEYBOARD * KEYBOARD_price);
