The function \"new\" allows us to allocate memory during compile time. True Fals

Question

The function "new" allows us to allocate memory during compile time. True False Consider the following class declaration: class patient_record {public: int age; string name; double service_charge;}; Implement the integer function "find_rec" which returns the index of the patient record with a name matching key in DB. If the name is not found in DB, -1 is returned. Consider the following prototype to help you write (code) this function: int find_rec(const patient_record * DB, const string & key, const int & count)

Explanation / Answer

False memory is allocated at run time it is dynamic memory allocation.

int find_rec(const patient_record *DB,const string &key,const int &count)
{
int result = -1;
int i;
patient_record record;
  
for(i=0;i<count;i++)
{
record = *(DB+i); //get the ith record from the starting address DB
if(record.name.compare(key) == 0)
{
result = i+1;
break;
}
}
return result;
}

Yes function delete is used to de-allocate memory allocated by new.
