How could a programmer make the variables in main available to other functions?
What will be an ideal response?
The programmer can pass the address of the variables to other functions, using either an explicit call (pass the address using the & operator to a pointer) or an implicit call using a reference variable. Either way, the function has access to main’s variables because the function has the variables’ addresses.
