Functions are said to be first class objects in C++. How is it possible to replicate the following pyhton code in C++?

def print_wrapper(a):
    print(a)

def execute_function(func, arg):
    return func(arg)

execute_function(print_wrapper, 'test_argument')

Please note that the function print_wrapper is passed as an argument into the function execute_function.
