you have 2 do-while loops but only one is finished with while!
each do must have an while as well!

one more tip:

do not include <iostream.h> reather include <iostream>do not use system("pause") but use cin.ignore();


your code:

char ERROR;
//...
 while (correct == ERROR); 

do you realise that all number except 0 are threated as true?
that is:

-4 is true
-445 is true
4 is true
109 is true
-98 is true
-54.45 is true
56 is true

ONLY 0 is false!

thanks,. so i completed the first loop. and my compiler wont work without the .h in the #include<iostream.h> and i get more errors wit hthe cin.ignor();
and what do you mean with the last part? i understand only 0 is false but i dont get what your reffering to. sorry.
and now im getting a ton of errors.
expected primary-expression before ';' token
expected `;' before '}' token
At global scope:

[codekiddy]

by last part I mean this:

for (i = 1; i <= correct; i++)

correct is not initialized so it can be false at program startup

correct = ERROR;

again neather of them is initialized.

initialize variable before u use it.

my compiler wont work without the .h in the #include<iostream.h>

that's strange.

i get more errors wit hthe cin.ignor();

it's not cin.ignor();

it is cin.ignore();

and now im getting a ton of errors.
expected primary-expression before ';' token
expected `;' before '}' token
At global scope:

not to hestitate you but you need to learn how to debug and understand errors.

now I'm litle tierd, it's 5:00h and I have to into bet.
hope someone will explain you until tomorow :)

cheers Morgan!
