0 10 20 30 40 50 60 70 80 90 100

this is the end result im tring to come up with can anyone help.


# include <iostream>
using namespace std;
int main ()
{
int across;
int down;
for ( across =0 ; across <=10 ; across ++)
for ( down =0 ; down <=10 ; down ++)
cout << across * down;
return 0;
}

this is where i ended up. missing something to allow it to display properly. this program is a multiplication table where I can enter a number and it will display the approperate diagram.

what does that mean ? i havent learned about that.

The problem is you have no spaces or newline characters in your program. Also, you have it set to print out columns, while it would be much easier to just make it print rows first, then use an endl.

Here's my (untested) edit:

Code:

---

# include <iostream>
using namespace std;
int main ()
{
  int across;
  int down;
  for (down =0 ; down <=10 ; down++)
  {
        for (across =0 ; across <=10 ; across++)
            cout << across * down << " ";
        cout << endl;
  }
  return 0;
}

edit: formatting issues

This block of code will get the desired results.

---------------------------------------------------------------------------------
#include <iostream.h>

int main()
{
int across;
int down;
for (across =0 ; across <=10 ; across ++)
{
for (down =0 ; down <=10 ; down ++)
cout << across * down << " ";
cout << endl;
}
return 0;
}
