[B]2 Dimensional Array [/B]

[whitey300]

As of now my program as the user input an expression like *2x and then the program outputs it as

*
2
x

I am wanting to display zeros next to the elements, 2 columns of zeros so the output will be

* 0 0
2 0 0
x 0 0

This is my code

int main()
{

string s;
cout << "Input the prefix expression.\n" ;
cin >> s;
cout << "The expression tree is:\n" ;

int row = s.length();
int col = 2;
int array[row][col];
int i, j, c;

for (j = 0; j < row; j++)
for (c = 0; c < col; c++)
for (i = 0; i < s.length(); i++)
{
cout << s[i] << array[row][col] << endl ;
}

it outputs

*2293584
22293584
x2293584
*2293584
22293584
x2293584
*2293584
22293584
x2293584
*2293584
22293584
x2293584

You can't define an array like that. You need to malloc one up.

And, you have a 3X3 matrix, and you are treating it like one, but your (incorrect) array definition is 3X2.

Finally, your outer loop should be the length iteration (or at least that's how 99% of programmers would do it)
