Question

I’m working on a project for school, and faced this elementary problem (it’s not part of the assignment, merely a set-back in the initial stage of the problem).

I am trying to create a pointer that points to an array. The array contains pointers, each of which points to a class object “Customer”.

Here is customer.h.
Here is customer.cpp.

Finally, here is my main, which is causing problems:

#include "customer.h"

int main () {
    Customer** c_array;
    c_array = new Customer*[10];
    cout << c_array[0]->getEnter() << endl;


    return 0;
}

Any ideas?

Here’s the error:

Segmentation fault: 11

Answer 1

Allocating an array of pointers does not allocate anything for what those pointers point to. So your statement:

c_array = new Customer*[10];

creates an array of pointers, but they point somewhere random (causing a segmentation fault when you try to dereference them). You will need to write a loop to initialise those pointers also.
