Which of the following are true with respect to the functionality provided by scanf and printf? Choose ONLY the correct options (one or more).   Question 7 options:   Although printf is not passed the pointer to an integer variable, it can still access the original integer variable's memory location to read its contents.   None of the other options given are true.   scanf needs to be passed the pointer to an integer variable because it needs to modify the original variable.   scanf's functionality can also be implemented so that it can be given the original integer variable directly without having to pass its address.
