Take the following example where i assume that table size
has been defined previosly but at some part of time i want
to change it..but the table size is defined in some other
module and you dont have an access to it.
#if TABLE_SIZE>200
#undef TABLE_SIZE
#define TABLE_SIZE 200
#elif TABLE_SIZE<50
#undef TABLE_SIZE
#define TABLE_SIZE 50
#else
#undef TABLE_SIZE
#define TABLE_SIZE 100
#endif
int table[TABLE_SIZE];
