Linear search
You implement this algorithm by iterating over each item, and checking if the item matches what you are searching for.
It is linear because it takes a linear amount of time to search for an item.
Answer:
The account record comprises of Invoice roll up summary fields.
Explanation:
The possible reason that this change was not permitted was that the account record comprises of Invoice roll up summary fields.
Invoice roll up summary fields: A roll-up summary field computes values from associated records, for example those in a linked list. a person or someone ca design a roll-up summary field to show a value in a master record by building the values of fields in a particular record.
The detail record must be associated to the master through a master-detail relationship. for instance, you want to show the sum of invoice amounts for all linked custom object records in an account’s Invoices related list. you can show the whole or sum in a custom account field refereed to as Total Invoice Amount.
Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.
