# Issue

I have a multi-dimensional array in C#, I have assigned the indices of the matrices by capturing input from a user, I am trying to implement a conditional structure that will let me print the rows of my matrix each on a separate line, for example if my array is A and A has a dimension of 3 by 3 then the code prints the first three elements on the first line, the next three elements on the next line and so on and so forth. I am trying to achieve this because it will be easier to understand the structure as a normal matrix and also build an entire matrix class with miscallenous operations.

**Code**

```
class Matrix{
static int[,] matrixA;
static void Main(string[] args){
Console.WriteLine("Enter the order of the matrix");
int n = Int32.Parse(Console.ReadLine());
matrixA = new int[n, n];
//assigning the matrix with values from the user
for(int i = 0; i < n; i++)
{
for(int j = 0; j < n; j++)
{
matrixA[i, j] = Int32.Parse(Console.ReadLine());
}
}
//the code below tries to implement a line break after each row for the matrix
for (int i = 0; i < n; i++)
{
for (int j = 0; j < n; j++)
{
if( (n-1-i) == 0)
{
Console.Write("\n");
}
else
{
Console.Write(matrixA[i, j].ToString() + " ");
}
}
}
}
}
```

How do I modify my code so that if the array has 9 elements and its a square matrix then each row with three elements are printed on a single line.

# Solution

I would use something like this for the output:

```
for (int i = 0; i < n; i++)
{
for (int j = 0; j < n; j++)
{
Console.Write(matrixA[i, j].ToString() + " ");
}
Console.Write("\n");
}
```

When the inner loop is done, that means one row has been completely printed. So that's the only time the newline is needed. (`n`

passes of the outer loop ==> `n`

newlines printed).
