I am having a problem with my program. We are supposed to ask for two numbers as input then half the larger and double the smaller. If the larger is odd then the smaller is added to an accumulator.

My problem lies (i'm guessing) somewhere in the functions.

Here is my code and below is my compile error.

Here is the compiler error.

ok fixed one problem and created another.

here is my new error.
