I have just begun my intro to programming class, so please bear with me. When I set my precision I receive an error of something like: cannot convert bool to std; I know it's got something to do with my first function. I thought the result of the function was stored as an integer, but apparently that's not right. How can I alter the function, given my limited knowledge, so I can setprecision. Any suggestions would be greatly appreciated. Thanks.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int getQuantity (int);
float totalCost (int, const float);
int main()
{
const float PC_COST = 995.00;
const float MEM_COST = 89.95;
const float ZIP_COST = 99.99;
const float PRINT_COST = 119.50;
int numberPCs, numberMem, numberZip, numberPrint,pc_quantity;
int mem_quantity, zip_quantity, print_quantity;
float pc_total, mem_total, zip_total, print_total, totalOrder;
cout<<"Enter the number of PC's:";
pc_quantity= getQuantity(numberPCs);
cout<<"Enter the number of memory cards:";
mem_quantity= getQuantity(numberMem);
cout<<"Enter the number of zip drives:";
zip_quantity= getQuantity(numberZip);
cout<<"Enter the number of printers:";
print_quantity= getQuantity(numberPrint);
cout<<"\n\n";
cout<<" New Wave Computer Company "<<endl;
cout<<" ***********************************"<<endl;
cout<<"Product"<<setw(25)<<" Cost each "<<setw(15)<<" Quantity "

pc_total= totalCost (pc_quantity, PC_COST);

return 0;
