Question

I am trying to read the third column from a file to catch the error using exception Handling in C++.

Let's say this is the file:

123 Laptop 1000.00 HP

124 Monitor 250.00 Dell

125 Textbook 49.99 Deitel

126a Tshirt 19.99 Macys

127 Glass 10.00 GlassCo

128 Candy TBD Hersheys <--- Trying to catch this error this Price

129 iPhone 250.00 Apple

130 Pants 79.99 Express

131 Chips 4.29 Ruffles

132 Keyboard 29.99 Apple

1.)How would I go about catching the TBD Price?

I have already caught the ID mistake. and the program can count the 1 mistake in the file.

2.) How would I get the average price ?

i tried this:

double averagePrice = 0.0;

vector<Product>products;
       for (unsigned int i = 0; i < products.size(); i++)
       {
           averagePrice += products.at(i).price;
       }
       averagePrice /= products.size();

cout << "Average price: " << averagePrice << endl;

Help would be immensele appreciated.
