Question

1.C++

Write a program that uses a structure named MovieData to store the following information about a movie: title, director, year released, and running time (in minutes). Include a constructor that allows all four of these member data values to be specified at the time a MovieData variable is created. Your program should do the followings:

A. creates two MovieData variables (namely, movie1 and movie2)

B. creates two pointers to the structure MovieData (namely, movie1Ptr and movie2Ptr) and initializes them with the addresses of the structure variables movie1 and movie2, respectively

C. uses movie1Ptr with the * and the dot operators to display the details of movie1

D. uses movie2Ptr with the -> operator to display the details of movie2

Answer 1

Code Screenshot:

Executable Code:

#include<iostream>
using namespace std;

//MovieData structure
struct MovieData{
//variables
string title, director;
int year, runningTime;
//constructor initializing all fields
MovieData(string titl, string dir, int yr, int time){
title=titl;
director=dir;
year=yr;
runningTime=time;
}
};

int main(){
//creating two MovieData objects named movie1 and movie2
MovieData movie1("Avengers: Endgame", "Joe Russo",2019,182);
MovieData movie2("Avatar", "James Cameron",2009,162);
//creating two MovieData pointers, pointing to each of the above objects
MovieData* movie1Ptr=&movie1;
MovieData* movie2Ptr=&movie2;
//using * and . operators, displaying details of first movie with movie1Ptr
cout<<"Title       : "<<(*movie1Ptr).title<<endl;
cout<<"Director    : "<<(*movie1Ptr).director<<endl;
cout<<"Released    : "<<(*movie1Ptr).year<<endl;
cout<<"Running Time: "<<(*movie1Ptr).runningTime<<endl<<endl;
//using -> operator, displaying details of second movie with movie2Ptr
cout<<"Title       : "<<movie2Ptr->title<<endl;
cout<<"Director    : "<<movie2Ptr->director<<endl;
cout<<"Released    : "<<movie2Ptr->year<<endl;
cout<<"Running Time: "<<movie2Ptr->runningTime<<endl<<endl;
return 0;
}
