"Process terminated with status -1073741819" simple program with vector - c++

Question

for some reason I get the "Process terminated with status -1073741819" error whenever I run my program, I've read that some people get this error because of something wrong with code-blocks/the compiler, i just wanted to know if there is anything wrong with my code before i go reinstalling compilers and such. I'm using code::blocks and the GNU GCC compiler.
my code creates a vector which stores 40 working hours in a week, and a vector inside that vector which stores letters representing the 5 people available in those hours.
Schedule.cpp:
#include <iostream>
#include "Schedule.h"
#include <vector>
#include <string>
using namespace std;
/// Creates a Vector which holds 40 items (each hour in the week)
/// each item has 5 values ( J A P M K or X, will intialize as J A P M K)
vector< vector<string> > week(40, vector<string> (5));
Schedule::Schedule(){
for (int i = 0; i<40; i++){
week[i][0] = 'J';
week[i][1] = 'A';
week[i][2] = 'P';
week[i][3] = 'M';
week[i][4] = 'K';
}
// test
cout << week[1][3] << endl;
}
header file:
#ifndef SCHEDULE_H
#define SCHEDULE_H
#include <vector>
#include <string>
using namespace std;
class Schedule
{
public:
Schedule();
protected:
private:
vector< vector<string> > week;
};
#endif // SCHEDULE_H
main.cpp:
#include <iostream>
#include "Schedule.h"
#include <vector>
#include <string>
using namespace std;
int main()
{
Schedule theWeek;
}

This is not a copiler bug.
You are getting a memory fault in your constructor.
There are several things wrong with your code, for example in your cpp you declare a global vector week which then is hiden in the constructor since the constructor will access Schedule::week .
Your cpp should be something like :
// comment out the global declaration of a vector week ...
// you want a vector for each object instantiation, not a shared vector between all Schedule objects
// vector< vector<string> > week(40, vector<string> (5));
Schedule::Schedule()
{
for (int i=0;i<40;i++)
{
vector<string> stringValues;
stringValues.push_back("J");
stringValues.push_back("A");
stringValues.push_back("P");
stringValues.push_back("M");
stringValues.push_back("K");
week.push_back(stringValues);
}
}
You get the memory fault in your code when you try to access your week vector for the first time :
week[i][0] = 'J' ;
At the moment you call that line of code, your Schedule::week vector has 0 elements inside it (so week[i] is already a fault).
