I have been developing in python for the last few years. C++ was something that I highly doubt I would ever need to learn but well lucks plays out in mysterious ways. Being in the final year of Electrical Engineering options of course I opted for a final year project in computer science because why make your life easier.
Coming to the point here is the first ever project that I implemented using C++.
This is an anime recommendation engine at its most basic form using almost all the basic elements the C++ has to offer.
It can act as a very good beginner project which can be used by you to build something on for your own course.
Problem Statement: Build a recommendation engine that:
- Asks the user to register
- Verifies the user by asking it to login
- Asks the user to answer two questions
- Recommends anime based on the answers
The Project can be extended to much more complex recommendations by simple adding more questions.
Lets dive into the code.
CODE
#include <iostream> #include <string.h> #include <iomanip> using namespace std; int main(void){ string name = "temp"; string password = "temp"; string login_name = "temp_1"; string login_password = "temp_2"; int input; string genre_in; bool air_in; int counter = 0; string output_name[2]; int output_score[2]; bool flag = false; struct { string name; string genre; int score; bool air; } anime[4][4]; struct { string name; string genre; int score; bool air; } database[4][4]; // name database[0]->name = "aot"; database[1]->name = "death note"; database[2]->name = "hero academia"; database[3]->name = "haikyu"; database[4]->name = "beyblade"; // genre database[0]->genre = "action"; database[1]->genre = "thrill"; database[2]->genre = "action"; database[3]->genre = "thrill"; database[4]->genre = "action"; // score database[0]->score = 10; database[1]->score = 8; database[2]->score = 10; database[3]->score = 7; database[4]->score = 5; //air database[0]->air = true; database[1]->air = false; database[2]->air = true; database[3]->air = true; database[5]->air = false; cout << "Welcome to anime recommednation engine !" << endl; cout << "Please register below to continue !" << endl; cout << endl; cout<<"Enter a user name: "<<flush; cin >> name; cout<< "Enter a password "<<flush; cin>>password; cout << " Thank you for registering !" << endl; cout << "Now you have to login !" <<endl; do{ cout<<"username: "<< flush; cin>>login_name; cout<<"password: "<< flush; cin>>login_password; if((password==login_password) && (name==login_name)){ cout<<"thank you logging in"<<endl; break; } else { cout<<"Please try again with correct information"<<endl; } } while (password!=login_password); cout<<"Welcome to the recommendtion engine!"<<endl; cout<<"what genre of anime you like ?" <<endl; cout<<"1- Action 2- Thrill (Enter 1 or 2): "<<endl; cin>>input; if (input == 1){ genre_in = "action"; } else if(input == 2){ genre_in = "thrill"; } cout<<"Do you want it to be on air ?" <<endl; cout<<"1- Yes 2- No (Enter 1 or 2): "<<endl; cin >> input; if (input == 1){ air_in = true; } else if (input == 2){ air_in = false; } for(int i = 0; i < 4 ; i++){ if(database[i]->genre==genre_in){ if(database[i]->air==air_in){ output_name[counter] = database[i]->name; output_score[counter] = database[i]->score; counter++; } } } for(int j = 0; j < 2 ;j++){ cout<<"Recommendation " << j << ": "<< output_name[j] << " Score: " << output_score[j]<<endl; } return 0; } The code is self explanatory and I am hoping comments are not needed to understand it. In case of any questions feel free to ask.
