3.5. Simple arithmetic

We mentioned at the start of this chapter that point of a program usually involves performing actions on data. By using standard mathematical symbols, arithmetic in C is easily readable.

Example 3-5. wages.c

int
main()
{
  int hours_per_day;
  int days_per_week;

  hours_per_day = 8;
  days_per_week = 5;

  printf("I work %d hours a week.\n", (days_per_week * hours_per_day) );

  printf("%d %d hour days\n", days_per_week, hours_per_day);

  return 0;
}
