repeating a sequence of code

Hello,

I am working on an assignment for a class, I have a program written as follows,

disp(' Choose an Option Below ');

disp(' 1 Convert Decimal Number to Binary Number');

disp(' 2 Convert Binary Number to Decimal Number');

disp(' 3 Exit');

n = input(' Enter Option Number You Desire: ');

switch n

case 1

fprintf(' Convert Decimal Number to Binary Number\n');

a = input(' Please enter a whole decimal number: ');

bradleyJohnsonD2B(a)

case 2

fprintf(' Convert Binary Number to Decimal Number\n');

b = input(' Please enter a binary string : ');

johnsonBradleyB2D(b)

case 3

fprintf( ' Thank you for using my program !!\n ');

otherwise

fprintf( ' You Selected an Invalid Option, Please Choose Again ');

end

I need this program to start over or repeat its self from the beginning for every option other than case three. how would I go about doing that.

Do you mean this?

n = 1;

while n ~= 3
    disp(' Choose an Option Below ');
    disp(' 1 Convert Decimal Number to Binary Number');
    disp(' 2 Convert Binary Number to Decimal Number');
    disp(' 3 Exit');
    n = input(' Enter Option Number You Desire: ');

    switch n 
        case 1 
            fprintf(' Convert Decimal Number to Binary Number\n');
            a = input(' Please enter a whole decimal number: ');
            bradleyJohnsonD2B(a)

        case 2
            fprintf(' Convert Binary Number to Decimal Number\n');
            b = input(' Please enter a binary string : ');
            johnsonBradleyB2D(b)

        case 3 
            fprintf( ' Thank you for using my program !!\n ');

        otherwise 
            fprintf( ' You Selected an Invalid Option, Please Choose Again ');
    end
end
