# All the sumIt* functions do the same thing:

def sumIt1(a, b)
  result = a + b;
  return result
end

def sumIt2(a, b)
  result = a + b;
end

def sumIt3(a, b)
  a + b;
end

# Start the main program --- note functions have to be defined before
# they get used.

puts(sumIt1(1,2))
puts(sumIt2(1,2))
puts(sumIt3(1,2))
