the for count command is not working. Turing says that the variable is not declared. Doesn't the count command not need to be declared Question

"for count" isn't a command.

"for i : 1..10" is though.

refer to examples in turing documentation -- for

what is wrong with this

var depth :int
var sum :int
get depth



for num: 1 .. depth
sum:= depth-3+2/num
exit when sum=num
put sum-num
end for

I don't know. What does the compiler say?

for num it says assigned value is the wrong type.

Integers don't like being divided. They love div though.

div will divide integers.floor,ceil,and round will divide 2 numbers to produce an integer of the result depending on the command

its because you are trying to divide an integer, which you cannot do unless you round it. an integer is a whole number, thus if you are dividing 3 by 2, you will get a decimal, which is not an integer

Which just means that you can't divide 3/2 and store it as an integer. 1.5 is not an integer. However, you may store that into a real.

Here is an example of Ceil,Dividing,Div, and floor.


Turing:

% Diving
put 5 / 2 % = Outputs 2.5 REAL
put 10 / 2 % = Outputs 2 REAL
put 21 / 2 % = Outputs 10.5 REAL
% Div { Divides without computing Remainders }
put 5 div 2 % Outputs 2 INT
put 10 div 2 % Outputs 5 INT
put 21 div 2 % outputs 10 INT
% Round
put round (5 / 2) % Outputs 3 INT
put round (10 / 2) % Outputs 5 INT
put round (21 / 2) % Outputs 11 INT
% Ceil {Rounds UP Always}
put ceil (5 / 2) % Outputs 3 INT
put ceil (10 / 2) % Outputs 5 INT
put ceil (21 / 2) % Outputs 11 INT
% Floor {Rounds Down Always}
put floor (5 / 2) % Outputs 2 INT
put floor (10 / 2) % Outputs 5 INT
put floor (21 / 2) % Outputs 10 INT
