Seriously?
Take a close look at the very first error (I actually get one previous one, on the scanf line) and the syntax coloring should give you an easy clue, specially when you compare it with the other if's following the first two.
Furthermore, on the same line, even with the inclusion of the stdbool.h header file, C doesn't know the word "OR" (or "or" for that matter) as an operand.
Beside that, you also need to check on properly terminating all your statements properly with a ";", this is C, not Pascal...
