There's nothing that I can see in your code that should be causing those errors. It would help if you posted the rest of the function.

EDIT: After looking at it again, it looks like you spelled reduction differently from how you declared it:

D:\Robot\MyFiles\user_routines.c:239:Error [1105] symbol 'redeuction' has not been defined

The symbol 'redeuction' has not been defined, only 'reduction' has been.

Also, for this error:
D:\Robot\MyFiles\user_routines.c:259:Error [1139] integer types required for bitwise XOR operator

the 'a^b' in C/C++/java is not actually a to the power of b. It's the XOR operator.

if you have two binary integers: a = 1011, b= 1101, a^b would be: 0110. XOR compares each binay digit of a with the corresponding digit of b. If the digits are different, a 1 is placed as the corresponding digit of the result, if they are the same, a 0 is placed.

If you need to do something like a^2, you should just do a*a. If you need actual exponentials then you have to use math.h or write your own function. If you use the c math library, pow(a, b) = a to the bth power.

EDIT #2: fixed the name of the power function
