Using the code in part I of this lab (included below): 1. Create a function to INPUT the information for the movie. Pass the empty structure in as a parameter. 2. Create a function to OUTPUT the information in the structure. Pass the filled structure in as a parameter. 3.

Question

Using the code in part I of this lab (included below):
1. Create a function to INPUT the information for the movie. Pass the empty structure in as a parameter.
2. Create a function to OUTPUT the information in the structure. Pass the filled structure in as a parameter.
3. Place the ENUM definition, STRUCTURE definition, and FUNCTION prototypes in a HEADER FILE (*.h).
Remove those definitions from the main program and include your header file in the main program file.
DECLARE the STRUCTURE VARIABLE as a LOCAL (not global) variable in the main program.
If you like to include the following line of code: system("pause");


Here is my code from the first part of the lab:



#include <iostream>

#include <string>

using namespace std;

//enum Ratings

enum Ratings

{

G = 1,
PG,
PG_13,
R,
NC_17

};

//structure movie

struct Movie

{

string name;

enum Ratings rating;

string year_produced;

string main_star;

char saw;

char liked;

};

//function to read rating from user

void read_rating(Movie &first)

{

char temp1;

int temp;

cin >> temp1;

temp = temp1 - '0';

switch (temp)

{

case 1:

first.rating = G;

break;

case 2:

first.rating = PG;

break;

case 3:

first.rating = PG_13;

break;

case 4:

first.rating = R;

break;

case 5:

first.rating = NC_17;

break;

default:

cout << "\nPlease enter a valid rating ";

read_rating(first);

}

}

//function to display rating of enum type

void display_rating(enum Ratings temp)

{

switch (temp)

{

case 1:

cout << "\nThis movie is rated G: General Audiences\n";

break;

case 2:

cout << "\nThis movie is rated PG : Parental Guidance Suggested\n";

break;

case 3:

cout << "\nThis movie is rated PG-13: Parent's Strongly Cautioned\n";

break;

case 4:

cout << "\nThis movie is rated R: Under 17 requires accompanying adult or adult guardian\n";

break;

case 5:

cout << "\nThis movie is rated NC-17: No one under 17 and under admitted\n";

break;

}

}

int main()

{

//create object of Movie

Movie first;

cout << "\nEnter name of Movie ";

//read name of movie

cin >> first.name;

cout << "\nEnter Rating of movie from the following\n";

cout << "\n1 - G\n2 - PG\n3 - PG-13\n4 - R\n5 - NC-17\n\n";

//read rating of movie

read_rating(first);

cout << "\nEnter year produced ";

//read year produced of movie

cin >> first.year_produced;

cout << "\nEnter main star of movie ";

//read main star of movie

cin >> first.main_star;

cout << "\nPress Y if you saw the movie else Press N if you didn't saw the movie ";

//read if user has saw the movie

cin >> first.saw;

cout << "\nPress Y if you liked the movie else Press N if you didn't liked the movie ";

//read if user liked the movie

cin >> first.liked;

//print information about movie

cout << "\n\nName of movie is " << first.name << endl;

cout << "\nThe movie is produced in year: " << first.year_produced << endl;

cout << "\nMain star of Movie is " << first.main_star << endl;

display_rating(first.rating);

if (first.saw == 'Y' || first.saw == 'y')

cout << "\nYou saw the movie\n";

else

cout << "\nYou did not see the movie\n";

if (first.liked == 'Y' || first.liked == 'y')

cout << "\nYou liked the movie\n";

else

cout << "\nYou did not like the movie\n";

cout << endl;

}

 

Expert Solution
Step 1

 

  • Create a function INPUT which takes a structure variable as parameter.
  • Pass structure variable using call by reference.

 

Complete INPUT function:

 

// Function definition for INPUT

 

void INPUT(Movie &first)

{

            cout << " Enter name of Movie ";

           

//read name of movie

 

cin >> first.name;

 

cout << " Enter Rating of movie from the following ";

 

cout << " 1 - G 2 - PG 3 - PG-13 4 - R 5 - NC-17 ";

 

//read rating of movie

 

read_rating(first);

 

cout << " Enter year produced ";

 

//read year produced of movie

 

cin >> first.year_produced;

 

cout << " Enter main star of movie ";

 

//read main star of movie

 

cin >> first.main_star;

 

cout << " Press Y if you saw the movie else Press N if you didn't saw the movie ";

 

//read if user has saw the movie

 

cin >> first.saw;

 

cout << " Press Y if you liked the movie else Press N if you didn't liked the movie ";

 

//read if user liked the movie

 

cin >> first.liked;

 

}

Step 2

 

  • Create a function OUTPUT which takes structure variable as parameter.
  • Pass structure variable using call by value.

 

Complete OUTPUT function:

 

/Function definition for OUTPUT

 

void OUTPUT(Movie first)

{

           

            //print information about movie

 

cout << " Name of movie is " << first.name << endl;

 

cout << " The movie is produced in year: " << first.year_produced << endl;

 

cout << " Main star of Movie is " << first.main_star << endl;

 

display_rating(first.rating);

 

if (first.saw == 'Y' || first.saw == 'y')

 

cout << " You saw the movie ";

 

else

 

cout << " You did not see the movie ";

 

if (first.liked == 'Y' || first.liked == 'y')

 

cout << " You liked the movie ";

 

else

 

cout << " You did not like the movie ";

 

cout << endl;

           

}
