Question

Write a C++ program that uses a structure named Movie to store the following. a. Title b. Director c. Year Released d. Running time (in minutes) e. Cost of production f. Revenue (first year). Create an array of type Movie of size 3. In your main program should then have in a loop (3 times) called a function called getData() and the purpose of this loop is to populate your array of Movie of size 3. Movie getData(); In the function getData() will prompt for user to enter the data for each of the elements shown above and then assign it to a struct. The function getData() will return a struct of type Movie as indicated by the prototype. The size of the array should be declared as a constant and the value of 3 here is just for simplicity of entering data. The value could had been 100 or 10,000 or so on and if the value for the constant is changed, there will be no need to change your code

c++ if you answer the question please write it line by line and not in paragrapth form.

Answer 1

CONCEPT..:

SINCE STRUCT IS TOOL TO COMBINE LOT OF DATAS TOGETHER... LIKE STRING INT FLOAT..ETC..

CALL BY REFRENCE IS USED FOR ACCESSING ORIGINAL VALUES DURING FUNCTION CALL ..OTHERWISE

CALL BY VALUE MAKES DUPLICATE VARIABLES AND WORK ON THEM SO NO CHANGE IN ORIGINAL VALUES..

//CODE SOLUTION:

#include <iostream>
using namespace std;

// declartion of the struct for all the variables of the movie ..
//struct is used to combine all the variables together...

struct movie
{   
//all the variables such as movie and director year combined together..
string Title;
string director;
string year_of_release;
int running_time;
double cost_of_production;
double revenue;
  
  
//Note here i have take title as string ..
//director as string .. and cost_of_production
// as double you can take any type if you want..
};

struct movie getData()
//this is a function to take input of the values fromm the user .. std... input

{

struct movie m1;
cout<<"Enter the Title of the movie\n";
cin>>m1.Title;
cout<<"Enter the director of the movie\n";
cin>>m1.director;
cout<<"Enter the year_of_release\n";
cin>>m1.year_of_release;
cout<<"Enter the running_time of the movie(in minutes.)\n";
cin>>m1.running_time;
cout<<"Enter the cost_of_production \n";
cin>>m1.cost_of_production;
cout<<"Enter the revenue of the movie \n";
cin>>m1.revenue;
  
return m1;
  
//we use dot operator here in order to find out input the values...

}

void printData(struct movie *m1)
//this is a function to show output.. of the values fromm the user .. std... output..

{
cout<<"The Title of the movie: "<<m1->Title<<"\n";
cout<<"The director of the movie: "<<m1->director<<"\n";
cout<<"The year_of_release of the movie: "<<m1->year_of_release<<"\n";
cout<<"The running_time of the movie: "<<m1->running_time<<"minutes"<<"\n";
cout<<"The cost_of_production of the movie: "<<m1->cost_of_production<<"\n";
cout<<"The revenue of the movie: "<<m1->revenue<<"\n";
  
double profit,loss;
  
if(m1->cost_of_production>m1->revenue)
{
cout<<"loss in the movie: "<<m1->cost_of_production-m1->revenue<<"\n";
}
  
else
{
cout<<"profit in the movie is: "<<m1->revenue-m1->cost_of_production<<"\n";
  
}
  
  
  
//Note in this function we have used call by refrence.. to access the data.. to original
//variable so since m1 is of pointer type so we have used the (->)of variable here..
//return type is also pointer of type struct here..
  
}
int main() {
  
struct movie m1[3];

for(int i=0; i<3; i++)
{
m1[i]=getData(); //call by value to get the data to our array..
}
  
  
//call the function by refrence to output the data...
  
for(int i=0; i<3; i++)
{
  
printData(&m1[i]); //we have used call by refrence here in this function to output
//values to fromm m1 variable
  
  
}
  

   return 0;
}
