Solve the following python programming problem given the following code:
# Definizione di una classe che implementa un "adder"
class Adder(object):
    def __init__(self, n=0):
        self.n = n   # Stato mutabile della classe (DANGER ZONE!!!)
    def __call__(self, m):
        return self.n + m
    
add5_istanza = Adder(5)
print(add5_istanza(1), add5_istanza(7))

# Definizione di una closure che implementa un "adder"
def make_adder(n=0):
    def adder(m):
        return n + m
    return adder
add5_function = make_adder(5)
print(add5_function(1), add5_function(7))

add5_istanza.n = 1
print(add5_istanza(1), add5_istanza(7))
print(add5_function(1), add5_function(7))
Given the above code, generate some markdown instructions for it.
