Allocate memory for an Array

I am trying to run this code below after I have compiled in C++.
The code do succesful when compiling.

When I doubleclick the program it starts but immediately the program encounters a problem and closes again.
What the code does is to read in values from a .txt file in arrays. As seen the arrays I am using has values like: Timearr[100000] etc...
If I change these to 10000 instead the program works and no problem occurs.

Could there be any idéas why this is happening ?

Code:

---

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <sstream>
#include <string> 

using namespace std;
int main ()
{
        std::string Datee;
        char Comma;
        int Timee = 0;
       
        std::string Datearr[100000];
        int Timearr[100000];
        int CountArray = 100000;

        ofstream MainFile;
        MainFile.open ("MainFile.txt");
        ifstream stockfile ("CCE.txt");
                       
        while        (    getline(stockfile, Datee, ',')  )                         
        {
               
                stockfile >> Timee;                     
                stockfile >> Comma;                 
                stockfile.get();                                // read in trailing newline character
        //////////////////////////////////////////////////////////////////////               
        // Read in File into Arrays (The Code is running now)
       

                CountArray = (CountArray - 1);        // CountDown for CountArray while all values is inserted for the arrays
                Datee = Datearr[CountArray];
                Timee = Timearr[CountArray];
               
  }                                                        // End of While Statement
        //////////////////////////////////////////////////////////////////////               
       

                return 0;
}                        // int main braces

The stack size that is available for your program is rather limited: just 1-2 MB.

For large arrays, you'll need to allocate memory dynamically. Which is tricky to manage, and that's why there's the std::vector class.

std::vector is also useful if you don't know how many items there will be in the array, as it can grow if you have more items. So you won't need to allocate 100000 of everything just in case and still be in trouble if it turns out that the "large number" is not enough.

You're putting too much data on the stack. Use std::vector so you can use dynamic arrays depending on how much data you need.

I think this solved the problem... I will experiment with the std::vectors... Thank you
