c++ file reading

[Juanse]

So, our programming teacher asked us to make a code for viewing and writing data over a file, it's supposed to be used by a videoclub(yeah, those old things that netflix replaced) and to store films on films.txt on a format ok id,name,year,rating,score,genre . using one line for each movie, using commas to separate each thing, I have to do this also for clients and employees and we have to use the getline function. The part over writing the file is easy, just ask for the data to the user and use 

outfile << id << "," << name << "," << year << ","<< rating << "," << score << "," << genre  << ","; 

What I'm clued in is how may I read the file

Thanks in advanced

#include <iostream>#include <fstream>#include <string>using namespace std;int main(){    ifstream infile ;    ofstream outfile ;    string movies ="movies.txt";    string clients ="Clients.txt";    string employees ="employees.txt"    int optionmenu=0;    while(optionmenu!=7)    {        cout << "Menu:" <<endl;        cout << "1_View employees" <<endl;        cout << "2_View movies" <<endl;        cout << "3_View clients" <<endl;        cout << "4_New employee" <<endl;        cout << "5_New movie" <<endl;        cout << "6_New client" <<endl;        cout << "7_Salir" <<endl;        cin  >> optionmenu;        switch(optionmenu)        {        case 1:            infile.open("employees.txt")            if (infile.is_open)            {            }        case 2:            infile.open("movies.txt")            if (infile.is_open())            {                            }        case 3:            infile.open("clients.txt")            if (infile.is_open())            {                            }        }            return 0;}

well I wont give you the answer because you would learn little from it, but what you want to reasearch is "string split" which will help you divide each line of text by the commas and "file read line" which will take one line at a time from a file using a while loop

 

so your file will look like

 

id,name,year,rating,score,genre

id,name,year,rating,score,genre

id, etc...

 

and your program will go line by line, and split the line by the commas, then take each word that is between the commas

hope that helps
