I am a student of computer engineering and I just left an exercise which is giving me several problems to solve it, I have to create a 4x5 matrix in windows forms and display all the elements of this, all right here but in addition to doing this I have to do the sum of the elements that are in the even rows and find the largest element of the middle column, here I leave what I carry in advance thanks.

```
{
int R, C;
int[,] numeros = new int[4, 5] { { 10, 45, 7, 23, 13 }, { 8, 76, 11, 58, 14 }, { 12, 55, 43, 32, 15 }, { 73, 99, 44, 2, 16 } };
for (R = 0; R < 4; R++)
{
for (C = 0; C < 5; C++)
{
txtnumeros.Text += numeros[R, C] + "\t";
}'
```
