Errr im practising and got stuck

Alright here it is;

code:

function moves (var a1, b1, c1, d1 : int) : int     a1 := a (i)     b1 := b (i)     c1 := c (i)     d1 := d (i) end moves

It wont work because "i" hasnt been declared yet, and here it is;

code:

for i : 1 .. 5     put "There are ", "moves from (", a (i), ",", b (i), " to (", c (i), ",", d (i), ")" end for

Here is the entire thing;

code:

var a, b, c, d : array 1 .. 5 of string var file : int open : file, "Data32.txt", get for i : 1 .. 5     get : file, a (i)     get : file, b (i)     get : file, c (i)     get : file, d (i) end for function moves (var a1, b1, c1, d1 : int) : int     a1 := a (i)     b1 := b (i)     c1 := c (i)     d1 := d (i) end moves for i : 1 .. 5     put "There are ", "moves from (", a (i), ",", b (i), " to (", c (i), ",", d (i), ")" end for

I just need to make the a1,b1,c1,d1 vars into those so I can make the calculation for later. This draws from a file so you cant really get the answers...

I don't get it. For one, your moves function doesn't return a value. And you're not calling your moves function anywhere. (Or do you do that later?)
Anyways, you've got two choices. Here they are:

code:

function moves (i : int, var a1, b1, c1, d1 : int) : int     a1 := a (i)     b1 := b (i)     c1 := c (i)     d1 := d (i)     %you need a result something somewhere in here.  That, or make it a proc end moves %to call it: for i : 1 .. 5     moves (i, someVariable, someOtherVariable, anotherVariable, finallyTheLastVariable) end for

or

code:

function moves (var a1, b1, c1, d1 : int) : int     for i : 1 .. 5         a1 := a (i)         b1 := b (i)         c1 := c (i)         d1 := d (i)     end for     %again, make it result something, or make it a proc end moves %and to call it moves (i, someVariable, someOtherVariable, anotherVariable, finallyTheLastVariable)

Hope that helps,

Well I couldn't do the calculation accuratly until I got those variables, but yes that works thank you again lolz.
