Pass by reference (Function within function)

[kkostas]

Let's say I have this function that I use to change some values in an instance of the class employer. I pass the instance by reference.
Q1) Is it possible to call calc_employer (Employer& emp) from within set_employer() to make some calculations and replace numerical values of the instance?
Q2) When control returns to set_employer(), will the changes made by calc_employer be available
Q3) Why should I avoid doing this?

void set_employer (Employer& emp1)
{
   ...
   calc_employer (emp1)
   ...
}

void calc_employer (Employer& emp)
{...}

PS: I guess this will enrage Duoas, but I beg for forgiveness Lord of C++.

A1) you have to declare (or define) calc_employer before calling it. example:

void calc_employer (Employer& emp);//a function declaration.

void set_employer (Employer& emp1)
{
   ...
   calc_employer (emp1)
   ...
}

void calc_employer (Employer& emp)
{...}

A2) yes.
A3) you shouldn't avoid this at all.

Thanks for the answer I was hoping for.
