declaring a multidimensional array

Hi all,

I would like your help

I am trying to declare a multidimensional arrays in the following way:

int PSF[57][57][65][65];

The full code has others variables.

I compile without problems, but when I run the program, appear a error:
Segmentation fault

I do not know what I am doing wrong ...


Someone know how solve this problem..???

Thanks

Manuel

The likely problem is that 57 * 57 * 65 * 65 * sizeof(int) is too much space to allocate on the stack. You can use a std::vector instead to avoid this.

Hi laserlight,

Thanks for your help


Can you help me?

I am new in C++, so I do not know how declare a std::vector with this size, can you indicate me how do it??

It might be along the lines of:

Code:

---

typedef std::vector<std::vector<int> > vector2d;
typedef std::vector<vector2d> vector3d;
typedef std::vector<vector3d> vector4d;

vector4d PSF(57, vector3d(57, vector2d(65, std::vector<int>(65))));

---

Of course, remember to #include <vector>.

The really simple answer is to just make it static.

static int PSF[57][57][65][65];
