Q on loading txt file in C++, and search algorithm

[mintominto82]

Hello, I am a very newbie (big emphasis on being a newbie) to c++. I read c++PRIMER but apparently, it did not provide much help.
I need a bit of help in codes loading txt file in C++. My frustration is that the file does not have any names of variables. The data looks as follows:
01/02/2004,1108.48
01/05/2004,1122.22
How do I assign the name to the variables in C++? (ie. how do I let C++ know that "Date" is the first column and "price" is the second colum?) Also, how do I categorize the date with " / " ? Float does not seem right, and using Char may cause problem too. (I need to compare the dates and find max, min, etc) I checked some postings, and one of them said to use stringstream, but I am not sure how to do so.

Also, I need to build a search "algorithm" that will have two variables, Date1 and Date2. And for any dates in between Date1 and Date2, I need the list of Dates and matching price displayed. Any hints which function I should use?

Any help would be appreciated.

Thanks:)

The disc file is just bytes of data. What you have to do is map those bytes to variables in your program. For example:

01/02/2004,1108.48

Your layout is:

int 01
char /
int 02
char /
int 2004
char ,
double 1108.48

So just use cin>> with variables of the correct type in this exact order.

Take a run at it and let me know how you get on.

Oops. I meant create an ifstream object and use it. cin is for keyboard input.

ifstream file("sample.txt");
file.open("sample.txt");  
                in >> int month;    
                in >> char /; 
                in >> int day;
                in >> char /; 
                in >> int year;
                in >> char , ; 
                in >> float price;

I did try, except it keeps giving me "expected primary-expression before "int" " error (same for char and float) when I try to compile. ???? And when and if I succeed in doing this, how does my data look like?

Does it look like matrix with 7 columns with month, " / ", day, " / ", year, " , ", price each column vector with 252 entries?

Also, how can I write these variables into arrays? there are 252 lines, and I want the columns to be month, day, year, price.
so it should be array[5][253]?

int main() {
    float Array[i][j];
    for (int i = 0; i < 5; i++)
    for (int j = 0, j <253, j++)
    {
        ???
 
        }
 
    return 0;
 
}

I tried to do it, but it is very confusing. what should be in "???" place in order to successfully produce an array?

any help is appreciated. thanks
