Trying to make a grid for fun, what am I doing wrong?


Code:
#include <iostream>
using namespace std;
int main()
{

    int row, column;
    row == 0;
    column == 0;
    {if (((row % 2) == 0)
    (while ((row <= 9)
    {while ((column <= 17);
    cout << "-";
    column ++)}));
    row ++ ;
    cout << endl) ;

    else if ((row <= 9)
    while ((column <= 17)
    {cout << "|   " ;
    column = column + 4));
    row ++;}
    return 0;
}}
I'm trying to make it look like this:
-----------------
| | | | |
-----------------
| | | | |
-----------------
| | | | |
-----------------
| | | | |
-----------------

I want to do it using while and for loops too.
Help is much appreciated!!

Here are errors I'm getting
Code:
10: error: expected primary-expression before ‚while‚
13: error: ‚((((unsigned int)row) & 1u) == 0u)‚ cannot be used as a function
13: error: expected `)' before ‚;‚ token
15: error: expected `;' before ‚)‚ token
17: error: expected primary-expression before ‚else‚
17: error: expected `;' before ‚else‚
EDIT:
For some reason its not coming out as I want it to look on here, its;
17 "-"
5 "|"
9 rows
17 columns

You really need to work on the formatting/indenting, that code is almost unreadable. It's also full of unbalanced parenthesis...at least I think, I can't tell because of the formatting. You have an else if inside a while, etc.

sorry here

Code:
#include <iostream>
using namespace std;
int main()
{

    int row, column;
    row == 0;
    column == 0;
    {if (((row % 2) == 0)

        (while ((row <= 9)
            
            {while ((column <= 17);
            cout << "-";
            column ++)}));
            row ++ ;

    cout << endl) ;

    else if ((row <= 9)
    
        while ((column <= 17)
        {cout << "|   " ;
        column = column + 4));

    row ++;}

    return 0;
}}
I just tried to condense it, hopefully this is better

What about this? I completely rewrote the code, I couldn't really figure out what you were trying to do in the example.

Code:
#include <iostream>
using namespace std;

int main()
{
   int row, column;
   for (row=0;row<9;row++)
   {
      for (column=0;column<16;column++)
      {
         if ((row % 2) == 0)
         {
            cout << "-";
         } else {
            if ((column % 5) == 0)
            {
               cout << "|";
            } else {
               cout << " ";
            }
         }
      }  
      cout << endl;
   }
   return 0;
}

I like the idea of the for loop, why does it seem easier with the for instead of the while??

Did you miss the "cout << endl" line in the code? It looks fine on mine:
Code:
$ g++ test.c 
$ ./a.out
