Just have a look at below examples and you will know what I am talking about.
|Code||Sentence that appears in my mind|
public int GetTotalCost(DataTable products)
For each product that is in products
get its price and add it to the total cost.
public int GetTC(DataTable dt)
For each i in range from 0 to dt.Rows.Count – 1 get ith
element of dt.Rows and get its price. Then add the price to tc.
Using OR mapping tools we can even replace DataTable with ProductCollection and DataRow with Product.
