Below are the instructions for my program and the source code. My program runs and works but I would like second opinions on how to make my program more efficient or if there are any loose ends in my source code.
Using functional decomposition, write a C++ program that will use a structure called MovieData to store the following information.
- Title
- Director
- Year Released
- Running time (in minutes)
- Production cost
- First Year Revenue.
Then use a value returning function called getMovieData() to read data to each
component of a struct variable as stated above. This function must return a
variable of type MovieData.
Also use a void function called printMovieData() to print each member of struct
in a nice format (with appropriate description). This function will accept a
pointer to type MovieData, that is, its prototype will be like this:
void printMovieData(MovieData *);
In your main() program, declare two variable of type MovieData with the following declaration: MovieData m1,m2;
And then call getMovieData() to assign value to each of m1 and m2.
Finally call printMovieData() on each of m1 and m2 to print values in each struct.
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
struct MovieData
{
string title;
string director;
int year_released;
int running_time;
int production_cost;
int first_year_revenue;
};
// Function prototypes
MovieData getMovieData();
void printMovieData(MovieData *);
int main()
{
// Variables
MovieData m1, m2;
MovieData *ptr1, *ptr2;
ptr1 = &m1;
ptr2 = &m2;
// Call getMovieData function to get information for both movies
m1 = getMovieData();
m2 = getMovieData();
// Call printMoviedata function to print information for both movies
printMovieData(ptr1);
cout << "\n";
printMovieData(ptr2);
system("PAUSE");
return 0;
}

MovieData getMovieData()
{
// Variables
MovieData temp;
// Prompt user for information
cout << "Enter the title of the movie: ";
getline(cin, temp.title);
cout << "\n";

getline(cin, temp.director);
cout << "\n";
cout << "Enter the year the movie was released: ";
cin >> temp.year_released;
cout << "\n";
cout << "Enter the running time of the movie in minutes: ";

cout << "\n";
cout << "Enter the production cost of the movie: $";
cin >> temp.production_cost;

cout << "Enter the movie's first year revenue: $";
cin >> temp.first_year_revenue;
cin.ignore();
