Practice 2:

A cell phone company offers three different price packages to its clients. In all of the
packages there is a fixed monthly fee; in addition, telephone calls are priced
according to per minute calling rate of that package. Package prices are as follows:
order of Package A, Package B, Package C
Monthly fixed rate 1.50 TL, 5.00 TL, 10.00 TL
Same operator calls 0.35 TL/min, 0.35 TL/min, 0.10 TL/min
Land line calls 0.40 TL/min, 0.35 TL/min, 0.20 TL/min
Other operator calls 0.60 TL/min, 0.35 TL/min, 0.30 TL/min

Write a MATLAB program that will do the following:

Get the package type (“A”, “a”, “B”, “b”, “C”, or “c”).
Readthenumberofminutestheclienthascalledsameoperatornumbers,land line numbers, and other operator numbers.
If any of the durations is negative, display a warning and stop.
Calculate and display the client’s bills

Solution:

Bellow code shows the how to pick best phone sector with given using inputs

%% Start to giving inputs from user
package = input('Select package ','s'); %% String input
same = input('Calls towards same operator numbers (minutes): '); %Integer inputs
land = input('Calls towards land line numbers (minutes): ');
other = input('Calls towards other operator numbers (minutes): ');
if same>=0 && land>=0 && other>=0 %% Checking the given inputs are positive or negative if it positive go to inside
    switch package(1) % switch expression
        case {'A','a'} %Case expressions two type 
            bill = 1.50 + same*0.35 + land * 0.40 + other * 0.60; % Calculate the bills in expression
            fprintf('Your bill is %f TL.\n',bill) % print the bills using &g with fprintf
        case {'B','b'}
            bill = 5 + same*0.35 + land * 0.35 + other * 0.35;
            fprintf('Your bill is %f TL.\n',bill)
        case {'C','c'}
            bill = 10 + same*0.10 + land * 0.20 + other * 0.30;
            fprintf('Your bill is %f TL.\n',bill)
        otherwise
            disp ('Invalid package. It must be one of A,B,C'); %If package is not A B C a b c
    end
else % Else statement for the negative numbers
    disp ('All durations must be zero or positive!'); %Display error message    
end

%% Start to giving inputs from user

package = input('Select package ','s'); %% String input

same = input('Calls towards same operator numbers (minutes): '); %Integer inputs

land = input('Calls towards land line numbers (minutes): ');

other = input('Calls towards other operator numbers (minutes): ');

if same>=0 && land>=0 && other>=0 %% Checking the given inputs are positive or negative if it positive go to inside

switch package(1) % switch expression

case {'A','a'} %Case expressions two type

bill = 1.50 + same*0.35 + land * 0.40 + other * 0.60; % Calculate the bills in expression

fprintf('Your bill is %f TL.\n',bill) % print the bills using &g with fprintf

case {'B','b'}

bill = 5 + same*0.35 + land * 0.35 + other * 0.35;

fprintf('Your bill is %f TL.\n',bill)

case {'C','c'}

bill = 10 + same*0.10 + land * 0.20 + other * 0.30;

fprintf('Your bill is %f TL.\n',bill)

otherwise

disp ('Invalid package. It must be one of A,B,C'); %If package is not A B C a b c

end

else % Else statement for the negative numbers

disp ('All durations must be zero or positive!'); %Display error message

end
