Alternative Sudoku Solver Input

[JakeIsBoss]

Hi. I just got a Sudoku solver up and running. There is one thing that's bugging me though. I have to type in the column, row, and value for each square in command prompt one number at a time (I normally don't use GUI), and it takes some time to do that. How could I set up a 9x9 thing of input boxes to make it a little easier and faster? Here is the input function i have right now:

void Input()
{
	Num_Known_Values = 0;

	while (1)
	{
		if (User_Input) // These several lines of code are what I want to replace.
		{
			Display_Contradictory = true;
			cout << "Column: ";
			cin >> Input_Column;
			cout << "Row: ";
			cin >> Input_Row;
			cout << "Value: ";
			cin >> Input_Value;
			cout << "\n";
			Input_Row--;
			Input_Column--;
		}

		else // This is just automatic random input for testing purposes.
		{
			Display_Contradictory = false;
			Input_Column = (rand() % (9 - 0)) + 0;
			//cout << "\nColumn: " << Input_Column + 1;
			Input_Row = (rand() % (9 - 0)) + 0;
			//cout << "\nRow: " << Input_Row + 1;
			Input_Value = (rand() % (9 - 0)) + 1;
			//cout << "\nValue: " << Input_Value << "\n";
		}

		if ( (Input_Value > 0 && Input_Value < 10 && (!Check_Contradictory_Values (Input_Column, Input_Row, Input_Value))) || Input_Value == 0)
		{
			Known [Input_Column][Input_Row] = Input_Value;
                        // This is where the number gets stored after being made sure it is a "legal" move in Sudoku.
                        //Ex. no two numbers can be in the same row or column.

			if (Input_Value = 0)
			{
				Possibilities_Reset();
				Eliminate_Possible_Using_Known();
			}
		}

		if (Find_Num_Known() >= 17 && !User_Input)
		{
			break;
		}

		else if (Find_Num_Known() >= 0 && Input_Value == 10)
		{
			break;
		}
		else if (Input_Value == -1)
		{
			Known_Reset();
			Possibilities_Reset ();
		}

		Display_Known();
	}
}
