- I hope you found the challenge rather easy.
The ten minute thing was just to scare you.
You really have to change both variable types to char.
A pointer variable must match the type of variable
it references, so, not only is line five changed,
but line six needs to be changed as well.
The value is assigned to pokey at line 8.
You don't need to change line nine, again,
because both these variable types match.
The other changes take place in lines 12 and 15,
where you need to specify the percent c placeholder
instead of percent d.
Save these changes, build and run, and it works.
