To sum all the values in the two-dimensional array, we need to iterate over all the rows and columns in the array. For each iteration, we add the value at that particular index to the sum. Since the rows and columns are 0-based indexed, we use "grid[row][column]" to access the value at that particular index. Therefore, the missing code should be "sum += grid[row][column]".
