Lost - Pointers, Structs, Functions

[StainlessSteelR]

This is what I'm suppose to do:

"Create a while loop to read in the corporate sales data from the pgm3.dat file and create a report listing data for each division as well as some of the summary data described in Programming Challenge 12 in the textbook. Inside the loop, for each set of division data read in:
a. Call a function named getDivision to read in the data for one division. Pass the Division pointer to this function to store the data in the memory locations allocated for the struct. Return this pointer to the main program.
b. Call a function named printDivision to write a line to the report file to display the division name, four quarterly sales amounts and the total sales for the year for that division. Pass the pointer to the division structure to this function.
c. Call a function named addDivision to add this divisions sales amounts to the corporate sales amounts. Pass the pointer of both the division and corporate structures to this function."

Other then the fact that I'm completely lost and don't know what it's asking for; my biggest problem at the moment is how do I pass the pointer into the function when the pointer is pointing to a struct?

Thanks, SSR

Do it the same as you would do with any other data object, such as a pointer to an int

void foo( Divison* pDiv)
{
  // blabla
}

int main()
{
    Division d;
    foo( &d );
}
