There is no standard practice for modeling multi-environment

chooses the best available option: 1. Exact/identity match 2. Trivial conversion 3. Promotion 4. Promotion + trivial conversion 5. Standard conversion 6. Standard conversion + trivial conversion 1)Promotions (Rank 2) 62 The following standard conversions count as promotions: • Integral promotion • unsigned short ➜ unsigned int or int (depending on your platform) • short ➜ int • char ➜ int point promotion • float ➜ doublePromotions (Rank 2) 63 void f( int ); // (1) void f( double ); // (2) int main() { short v = 42; f( v ); } // Calls (1) (integral promotion, rank

go to a promotion. You will also see a series of four tabs: [Promo], [Rules], [Stores] and [Codes]. 6.6.3. Promo tab At the top is general information about this promotion. Each promotion has an ID determine what actions should be taken in the promotion. Each promotion can have multiple rules, and each rule can have multiple conditions and actions. If a promotion had multiple rules, they would all be checked product stores in which this promotion is active. You can add additional stores here or delete them. 6.6.6. Codes tab The codes tab is used to associate codes for a promotion, similar to coupon codes.
