Hi guys,

I was wondering if some1 out there could help me a little with my c++ work i gotta do!? Im a bit of a c++ rookie and am having issues setting up a multi-dimensional array in which the user can input the rows and columns. Its a relatively simple program (to which loads more has to be added!) but I cant even get this bit to work. Any help would be greatly appreciated!

int main()
{
int dx,dy;

cout << "Enter the width of the matrix\n";
cin >> dx;
cout << "Enter the height of the matrix\n";
cin >> dy;

int MyArray[dx][dy][5] = {0};

for (int i=0; i<dx; i++)
for (int j=0; j<dy; j++)
for (int k=0; k<5; k++)
{
cout << "MyArray[" << i << "][ " << j << "]: ";
cout << MyArray[i][j][k] << endl;
}
return 0;
}

In the program that u had given..
int main()
{
int dx,dy;

cout << "Enter the width of the matrix\n";
cin >> dx;
cout << "Enter the height of the matrix\n";
cin >> dy;

int MyArray[dx][dy][5] = {0};

for (int i=0; i<dx; i++)
for (int j=0; j<dy; j++)
for (int k=0; k<5; k++)
{
cout << "MyArray[" << i << "][ " << j << "]: ";
cout << MyArray[i][j][k] << endl;
}
return 0;
}



int MyArray[dx][dy][5] = {0};

Is the mistake..
An array can never be assigned to a single element.
Dont give that "=0"at the end ..
That will do.

Dont give that "={0}"at the end ..
That will do.

And u will get your required output.

It looks like you want to initialize the elements to zero. C++ should automatically do that for you, so there is no need for the assignment statement (plus it should be illegal).

There is no problem in above statement. You can very well do that.

Only global arrays get initialized automatically not the local one's.

I don't think so Wiz.
