Load data from file

Question

I got something like this

int main(){
    char N[20];
    int day,month,year,hour,minute,length;
    char group[30],description[100];
    std::cin>>N;
    std::ifstream data(N);
    while(!data.eof()){
    data>>day>>month>>year>>hour>>minute>>length>>group>>description;
    }
return 0;
}

and i got data in file in this form

23 12 2017 19 25 88 bussiness meeting meeting about new product

it's no problem to put integers into variables but i want to put "bussiness meeting" into group and "about new product" into description and the same thing while saving data in file.

how are you suppose to delimit the fields if there are no quoting involved? — Jean-François Fabre, Dec 23 '17 at 20:46
To repeat the question: How do you know it is "business meeting" and "meeting about new product", rather than "business" and "meeting meeting about new product", or "business meeting meeting" and "about new product"? — Martin Bonner supports Monica, Dec 23 '17 at 20:58

Make a lot of your defects go away by using `std::string` for text not character arrays. — Thomas Matthews, Dec 23 '17 at 21:09
i don't. that's why i want to find solution how can i read and save data — bluzazkapturem, Dec 23 '17 at 21:09
You may have buffer overflow, because you are not limiting the amount of text read into a variable. — Thomas Matthews, Dec 23 '17 at 21:10
@bluzazkapturem you CAN'T read the data the way you want, because the file simply doesn't contain enough information to accomplish what you want. The file is badly designed. If the `group` and `description` strings were actually delimited, you would have a fighting chance. But they are not, so you dont — Remy Lebeau, Dec 23 '17 at 22:24

Add " before and after group and description strings. But you need to know that if you going to want to load it, you going to need to parse it somehow. As other people said use std::string with C++
