Real-Life Examples

Here's a real-life example of using different data types, to calculate and output the total cost of a number of items:

Example

  // Create variables of different data types
int items = 50;
double
  cost_per_item = 9.99;
double total_cost = items * cost_per_item;
char
  currency = '$';

// Print variables
cout << "Number of items: " <<
  items << "\n";
cout << "Cost per item: " << cost_per_item
  <<
  currency << "\n";
cout << "Total cost = " << total_cost << currency
  << "\n";
