Question

Here is the source code:

int main() {
    int secondsInYear = 366*24*60*60; // Equals 31,622,400
    short int data[secondsInYear];
    FILE * pFile;
    pFile = fopen ("stat", "r");
    fread(data, sizeof(short int), secondsInYear, pFile);
    fclose(pFile);
}

on line fopen("stat", "r") it gives me the segmentation fault error! If I read secondsInYear/10 characters it will execute without any problem, So what seems to be the problem? And what’s the solution?

Answer 1

You’re creating a massive array on the stack. So you are hitting a stackoverflow. 🙂

You should dynamically allocate that array instead.

short int *data = new short int[secondsInYear];

and be sure to delete it later:

delete[] data;
