C++ Programming Lab STRUCTURES

I'm gonna be posting every day solutions. I've decided to start in order with C++. Beginning with structures. Here you have some exercises from the Pearson's Starting out with C++ chapter 11. This is an intermediate to advance book, although the first 10 chapters are the basics of the language.

• Define a new type called  POINT that is a structure consisting of two fields,  x and  y , both of type  double . 

struct POINT

{

double x;

double y;

};

•  Define a new type called  POINT3D that is a structure consisting of three fields,  x ,  y and  z , each of type  double .

struct POINT3D

{double x,y,z;};

• Define a new type called  ADDRESS that is a structure consisting of seven fields,  suiteNumber ,  streetNumber ,  street ,  city ,  province ,  postalCode ,  country , all of type  string .

struct ADDRESS

{

string suiteNumber,streetNumber, street, city, province, postalCode,country;

};

•  Define a new type called  DATE that is a structure consisting of three  int fields,  dayOfMonth ,  month and  year .

struct DATE{

int dayOfMonth,month,year;};

• Assume that the type  NAME has already been defined. Define a new type,  SREC that is a structure consisting of two fields:  name (a NAME ) and  grade (a  string ). 

struct SREC

{

NAME name;

string grade;

};

• Declare a structure whose tag name is Book and that contains exactly three fields (or members), each of type int. The first field is nCopies, the second field is nPages and the third field is nAuthors.

struct Book

{

int nCopies, nPages, nAuthors;

};

•  Declare a structure whose tag name is DrawnLine and that contains exactly two fields (or members). The first field is letter and is of type char, the second field is number and is of type int.

struct DrawnLine

{

char letter;

int number;

};

•  Declare a structure whose tag name is Money and that contains exactly two int fields, dollars and cents. 

struct Money

{

int dollars, cents;

};

•  Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum, both also strings, year, an int, clockSpeed, a double, cores, an int, ram, an int and finally storage an int.

struct Server

{

string manufacturer, model, serialnum;

int year,cores,ram,storage;

double clockSpeed;

};

•  Given the declaration of a structure whose tag is Book write the declaration of a Book variable, bestSeller.

Book bestSeller;

•  Given the declaration of a structure whose tag is ADDRESS, write the declaration of two ADDRESS variables, billing and shipping.

ADDRESS billing;

ADDRESS shipping;

•  Given the declaration of a structure whose tag is DATE write the declaration of the following variables enrolled_on, paid_on, and completed_on, each of which is of type DATE..

DATE enrolled_on, paid_on,completed_on;

• Given a structured type Money declare the following variables of that type: revenue, expenses, and profit. 

Money revenue, expenses, profit;
