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.
Explanation / Answer
you can define your own type of exception using methods like
your average logic looks good other than casting problem into double
