a code that compute numbers and numbers does not !

greetings all,

the following code I've created to compute an amount. whenever I try number of years let's say 2 it will compute correctly. However, when I want to compute something like 10 years it wont work ! please can you adivse

p = input('enter the amount you want to deposit initially:');

n = input('enter number of years:');

t = input(['enter the frequency of interest compounding\n'...

'type 1: for annually\n'...

'type 2: for semi annually\n'...

'type 4: for quarterly\n'...

'type 12: for monthly\n']);

r = input('enter the interest rate:');

switch n

case (1)

a = p*((1+((0.01*r)/t))^(n*t));

disp(['annually:',num2str(a)]);

case (2)

a = p*((1+((0.01*r)/t))^(n*t));

disp(['semi annually:',num2str(a)]);

case (4)

a = p*((1+((0.01*r)/t))^(n*t));

disp(['quarterly:',num2str(a)]);

case (12)

a = p*((1+((0.01*r)/t))^(n*t));

disp(['monthly:',num2str(a)]);

end

I am assuming you want to compute interest based on the frequency of compounding.

Your switch statement is with respect to n (number of years) when it should actually be with respect to t (frequency of compounding).

switch t
   case(1)

   case (2)

   case (4)

   case(12)
end

This is why it fails for n=10 in your code as there is no case corresponding for this input.
