Question

Using C++

Many software applications use comma-separated values to store and transfer data.

In this program, you are asked to implement the movie_call function that will parse a string of the above structure into the corresponding movie name, rating, and movie length.

ex: In "movie name, rating, length", the movie name is "movie name", the rating is "rating", and the length of the movie is "lenght".

This is the code:
#include <iostream>

#include <string>

using namespace std;

/*

Replace the function body with appropriate statements to movie_call

a string of movie details into its corresponding movie name, rating,

and length.

*/

void movie_call (string movie, string& name, string& rating, string& length) {

int comma, comma1;

          comma = movie.find(",");

          name = movie.substr(0, comma);

          movie = movie.substr(comma + 1);

            comma1 = movie.find(",");

            rating = movie.substr(0, comma1);

          length = movie.substr(comma1 + 1);

}

int main() {

string movie_details;

cout << "Please enter information for one movie of your choice: ";

getline(cin, movie_details);

//Add appropriate statement(s) to call the movie_call function

//and display the name, rating, and length

return 0;

}

Answer 1

#include<iostream.h>

#include<string.h>
void movie_call (string movie, string& name, string& rating, string& length) {

int comma, comma1;

         comma = movie.find(",");

         string name = movie.substr(0, comma);

         string movie = movie.substr(comma + 1);
 
         comma1 = movie.find(",");

         int rating = movie.substr(0, comma1);

         int length = movie.substr(comma1 + 1);

}

int main() {

string movie_details;

cout << "Please enter information for one movie of your choice: ";

getline(cin, movie_details);


movie_call (string movie, string& name, string& rating, string& length);
cout<<name<<endl;
cout<<rating<<endl;
cout<<length<<endl;
return 0;

}
