Real-Life Example

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;
float
  cost_per_item = 9.99;
float total_cost = items * cost_per_item;
char
  currency = '$';

// Print variables
printf("Number of items: %d\n",
  items);
printf("Cost per item: %.2f %c\n", cost_per_item, currency);
  printf("Total cost = %.2f %c\n", total_cost, currency);
