5 errors im getting

JEvans1234 (17)
the errors im getting are:

In function 'int main()':

error: expected 'while' before '}' token
error: expected '(' before '}' token
error: expected primary-expression before '}' token
error: expected ')' before '}' token
error: expected ';' before '}' token

these errors are all occurring on line 132.

as you may also notice it is not 100% complete that is because i am building it up as i go and have been writing it for a couple of evenings.

any help would be highly appreciated

The problem clearly lies in all those messed up brackets/braces (whatever they're called), but it's impossible to debug this, because the indentation sucks. So first fix that, then the problem will be obvious, I think.

I agree the indentation sucks. The problem though is that you are missing the while in your do-while loop. It should be after the curly bracket on line 131. So something like

} while (true);

That would be the missing while while
The missing '(' (
The missing expression true
The missing ')' )
And the missing ';' ;

have not included the last two which are for the 'do' and the 'int main()'

I agree the indentation sucks. The problem though is that you are missing the while in your do-while loop. It should be after the curly bracket on line 131. So something like

} while (true);

That would be the missing while while
The missing '(' (
The missing expression true
The missing ')' )
And the missing ';' ;


this seems to have fixed it. thanks
