    error problems

    I am getting an undeclared identifier error when everything is declared correctly:

    const int bigger = 150000;
    int bubbleArray[bigger];
    BubbleSort(bubbleArray, size);
    #ifndef H_SORTS
    #define H_SORTS
    #include <iostream>
    using namespace std;
    class sorting
    	void BubbleSort(int array[], int length);
    Can anyone help?

    Post more code, post the exact error, show which line number the error refers to.

    Since BubbleSort is a member of the sorting class, you should probably be calling it from inside another member function, or you should call it from an instance of sorting.

    Are you calling on your function from within your structure?

    You may not be calling on your structure's members. For example, sorting.BubbleSort instead of BubbleSort.

    Edit: jlou has a valid point, also.

    Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
