Out putting 2d arrays to text files

[sjaco]

i need an application that output a list of data to a text file. i have it set to save all of the data into arrays but it will not output the arrays to a .txt file. All i get is 0x22fed0 in the txt. How do i get it to output the entire array?

Post your code

What u get is the address to the array. do iterate it using a for loop.

What type of data is the array. char? int? The array variable itself is nothing bat a pointer to that specified type.

int Slab[50]

Slab[20] = 100;
Slab[20] will give the value 100 and it is an integer

I will let you work the rest out.

I must admit that this has the feel of an unstudied university assignment about it.
There are far to many unqualified programmers with university degrees ;)

Study hard.

array is not eq to pointer!

See Peter van der Linden, Expert C Programming. for more details.

No, but in a lot of situations they can be treated in the same mannor and I think this is one of them.

int *pointer = new int[50];
int array[50];

/* This is all valid */

pointer[20] = 100;
array[20] = 100;

*(p+21) = 101;
*(array+21) = 101;

/* but */

if (sizeof pointer != sizeof array) // This is true
{
    cout << "Size of pointer and array are different!" << endl;
}

/* and interestingly */

    delete[] pointer;
    pointer = array;

    if (p == array) // This is true
    {
        cout << "p == array\n";
    }

    if (&pointer != &array)  // This is true but in fact wont compile in C++ 
                             // because &pointer and &array have different types
    {
        cout << "&p != &array\n";
    }
