The #define preprocessor allows us to define symbolic names and constants. A quick example
#define PI 3.14159This statement will translate every occurance of PI in the program to 3.14159. Here is a more complete example:
#define PI 3.14159
main()
{
int r=10;
float cir;
cir = PI * (r*r);
}
This feature is partically usefull for defining 'magic' numbers.
