Im learning C form some cheap book, and writing short programs just to see if i understood how the command works.
Well here is a simple program that won't compile:
# include <stdio.h>

main ()
{
char ans;

/* Get correct input fromn the user, loop until the input is correct (y or n) */

do {

printf ("Is your printer turned ON? ( 'y' or 'n' )");
scanf (" %c", ans);
while ((ans != 'y') && (ans != 'n'));
}

/* Use a conditional to tell waht is happening once the correct input was entered */

/* line18 */ (ans == 'y') ? (printf ("I will start printing now.\n")) : (printf ("Turn on the printer and run the program again please.\n"));
return 0;
}

Here is the output from the compiler:
--(Sat Nov 9, 16:56:55)--(nskl@SlackBox:~/programming)$ gcc -o dowhile dowhile.c
dowhile.c: In function `main':
dowhile.c:18: parse error before `('
--(Sat Nov 9, 16:57:04)--(nskl@SlackBox:~/programming)$


I'm thinking it must be something simple... But i tried rewriting the program, changing it around, even using two if statements instead of the conditional, but i can't get it to work. Can anyone point me to waht is wrong here??
Thank you

I haven't looked at it all but let me give you one that stands out. Then see how you go from there. look at the location of your while in relation to your do.

It is either

do
<statement>
while

or

do{
<1 or more statements>
}while

also --and I haven't looked in a manual-- the scanf looks a little hokey. I think that it should be something more like

scanf (" %c", &ans);

alternately, you might do your decl like this

char ans[1];

Thank you, i moved while statement out of the do loop and it works well.
My mistake.
Thanks again
