retriever% cc201 test3.c proj3.cSince you do not have a copy of the source code for test3.c, you should compile your program using test3.o instead:
retriever% cc201 test3.o proj3.c
    #include <math.h>
  
  Otherwise, your program can behave very strangely.  You should
  really write your own power function for integers (pow takes
  double parameters and returns a double), it's just one for loop.
  Relying on C to do the type conversion for you can cost you a lot
  more time than writing a simple for loop.
