Bit. The smallest item of data is a single binary digit (a bit), either 0 or 1.
Character. Multiple related bits are combined to form a character. A bit is the basic unit of primary and secondary storage, and a character is the basic unit for human conception.
Field. It’s a meaningful collection of related characters.
Record. Multiple related fields are combined to form a record.
File. Multiple related records are combined to form a file. A file is a number of related records which are treated as a unit. Every record in a file has the same set of fields. Each record in a file is identified, for storage and retrieval purpose, by a key field whose contents are unique for each record in a file. In case of an employee file, employee-code field may serve as the key. In case of an employee file, employee-code field may serve as the key field.
Database. Multiple related files are integrated to form a database. A database is a collection of logically related data elements from multiple files.

The copy constructor is also involked when a function generates the temporary object that is used as the function's return value. With this in mind, consider the following output:
constructing nomally
constructing normally
constructing copy
This output was created by the following program. Explain why, and describe precisely what is occuring.
#include
using namespace std;
class myclass {
public:
myclass();
myclass(const myclass &o);
myclas f();
};
// Normal constructor
myclass::myclass()
{
cout << "Constructing normally\n";
}
// Copy constructor
myclass::myclass(const myclass &ocout << "Constructing copy\n";
}
// Return an object.
myclass myclass::f()
{
myclass temp;
return temp;
}
int main()
{
myclass obj;
obj = obj.return 0;
}

Given this particular defined class;
class strtype {
char *p;
int len;
public:
char *getstring() { return p;}
int getlength() { return len;}
add two constructor functions. Have the first one take no parameters. Have this one allocate 255 bytes of memory (using new), initialize that memory as a null string, and give len a value of 255. Have the other constructor take two parameters. The first is the string to use for initialization and the other is the number of bytes to allocate. Have this version allocate the specified amount of memory and copy the string to that memory. Perform all necessary boundary checks and demonstrate that your constructors work by including a short program.

Imagine a situation in which two classes, called pr1 and pr2, shown below, share one printer.Further imagine that other parts of your program need to when the printer is in use by an object of either of these two classes. Create a function in C++ called inuse() that returns true when the printer is being used by either and false otherwise. Make this function a friend of both pr1 and pr2.
class pri1 {
int printing; //...
public:
pr1 () {printing = 0}
void set_print (int status) {printing = status;}
// ...
};
class pr2 {
int printing;
// ...
public:
pr2 () {printing = 0;}
void set_prt status) {printing = status; }

When an object of a derived class is assigned to another object of the same derived class, is the data associated with the base class copied? To find out, use the following two classes and write a program that demonstrates what happens.
class base {
int a;

void load_a(int n) { a= n; }
int ge() { return a;}
};
class derived : public base {
int b;
