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;
}
