Answer:
The answers to 1st question and part 2A is given. However, the 2B is not given complete and thus cannot be answered.
Explanation:
UNION is a keyword used in C Language to have a commonly shared memory that can be used by multiple elements. It is a data-type that allows different data types to use the same shared memory location.
Importance: If you want to minimize the use of memory by sharing it between different datatype variables, then use UNION. For Ex. Let's suppose I want to use 2 variables a and b of type char and int respectively. Now, suppose int takes memory space of 2 bytes and char takes 1 byte then the total amount of memory needed = 2 + 1 = 3 Bytes. But, we want to first make use of a, and once done, we want to declare variable b. We can limit the memory use by declaring a memory space of 2 bytes (max of a and b). First, we can use this space to store the int variable and when done with it, we can use it to store the char variable.
PART 2A
typedef struct{
int partNum;
char partName[25];
} partin;
#define Partin partin
The answer is visual hierarchy :)
If workExperience >= 2 or CollegeDegree is true:
print “Application accepted”
else:
print “Application denied”
The way a particular application views the data from the database that the application uses is a sub-schema.
<h3>What is Database?</h3>
A Database may be defined as a process of collecting data and information that is principally assembled for quick search and recoupment by a computer.
The sub-schema is the reasoning elucidation of that section of the database which is applicable and accessible to a specific application. This type of database is common to two or more applications.
Therefore, the sub-schema is the way through which a particular application views the data from the database that the application uses.
