Answer 1

What do you want to achieve?
Sum of 2d array?

Answer 2

if you are passing array this way, you have to specify one of it's dimensions (columns):
int RowSum(int a[][10], int Row){
}

Then you have to create array:
int arr[10][10];
Assign some values to that array:
for(int i = 0; i < 10; i++){
for(int j =0; j<10;j++){
arr[i][j] = i+j;

Optionally, output them:
cout<<arr[i][j]<<" ";
}
cout<<endl;
}
Pass array, and Row that you want to sum and use:
cout << RowSum(arr,5);

Answer 3

It is not working cuz you are not passing any 2D array to this function

Btw, D2 is unknown, d1 and d2 are not used
