can't seem to get the value-returning function right...

trojan1987 (4)
I haven't finished my program yet, but the errors say, "local function definitions are illegal" for my functions...I don't know what to do, does anyone have any suggestions? Thanks



#include <iostream>
#include <fstream>
using namespace std;
char mealType (char);
double mealCost (double adultMeal,double childMeal);
double TaxTip (double mealCost);
double Bill (double, double);

int main()
{
int numAdults, numChildren;
double childMeal, adultMeal;
char type;
char weekend;

ifstream infile;
ofstream outfile;
infile.open("C:\\TEMP\\cateringdata.txt");
if(!infile)
{cout<<"File not found."<<endl;
outfile<<"Program terminates.";
exit(1);
}
outfile.open("C:\\TEMP\\outCatering.txt");
while(!infile.eof())
{
infile>>numAdults>>numChildren;
if( numAdults && numChildren <=0)
{outfile<<"# of Adults : Number of guests is invalid."<<endl;
outfile<<" # of Children: Number of guests is invalid."<<endl;}
else
outfile<<"# of Adults :"<<numAdults<<endl;
outfile<<"# of Children:"<<numChildren<<endl;
infile>>type;



double mealCost(double adultMeal, double childMeal)
{ mealCost=((adultMeal * numAdults)+ (childMeal * numChildren));
outfile<<"Total Meal Cost:"<<mealCost<<endl;}
double TaxTip(double mealCost)
{TaxTip=(mealCost*(.18));
outfile<<"Tax and Tip:"<<TaxTip<<endl;}
double Bill(double mealCost, double TaxTip)
{Bill= mealCost+TaxTip;
outfile<<"Bill: "<<Bill<<endl;}



char mealType( char type);
{ if (type == 'D' || 'd')

{adultMeal= 15.80;
childMeal= (.6 * 15.80);
outfile<<"Meal Type: Deluxe"<<endl;
outfile<<"Adult Meal Cost:"<<adultMeal*numAdults<<endl;
outfile<<"Children Meal Cost:"<<childMeal*numChildren<<endl;}

else if (type == 'S' || 's')
{adultMeal = 11.75;
childMeal = (.6 * 11.75);
outfile<<"Meal Type: Standard"<<endl;}

else outfile<<"Meal Type: Unidentified"<<endl;}


infile.close();
outfile.close();
return 0;
}
}

else outfile<<"Meal Type: Unidentified"<<endl;}


infile.close();
outfile.close();
return 0;
}
}

I think the problem is this part: 
1

3
4
5
6
7
8
9
 
double mealCost(double adultMeal, double childMeal)
{ mealCost=((adultMeal * numAdults)+ (childMeal * numChildren));
outfile<<"Total Meal Cost:"<<mealCost<<endl;}
double TaxTip(double mealCost)
{TaxTip=(mealCost*(.18));
outfile<<"Tax and Tip:"<<TaxTip<<endl;}
double Bill(double mealCost, double TaxTip)
{Bill= mealCost+TaxTip;
outfile<<"Bill: "<<Bill<<endl;}

Perhaps it should be this: 
1
2
3
4
5
6
7
8
9
10
 
double adultMeal, childMeal;
double mealCost(adultMeal, childMeal);
{ mealCost=((adultMeal * numAdults)+ (childMeal * numChildren));
outfile<<"Total Meal Cost:"<<mealCost(adultMeal, childMeal)<<endl;}
double TaxTip(double mealCost)
{TaxTip=(mealCost*(.18));
outfile<<"Tax and Tip:"<<TaxTip<<endl;}
double Bill(double mealCost, double TaxTip)
{Bill= mealCost+TaxTip;
outfile<<"Bill: "<<Bill<<endl;}

When I tried to debug it, I got these two errors that I can't figure out where the problem is:

1>c:\desktop\cateringlab6\cateringlab6\lab6.cpp(51) : error C2065: 'adultMealcost' : undeclared identifier
1>c:\desktop\cateringlab6\cateringlab6\lab6.cpp(52) : error C2065: 'childMealcost' : undeclared identifier


Any help would be much appreciated, thank you!
