How to display if user is correct or close to combination?

[TannerWhale]

I've been working on Mastermind for sometime now. I've gotten teh numbers to display and move up to the next line when the first line is complete. However, I do not know how to display how many the user has gotten right. For example:

7781 **--

the * shows that the user is right and the -- shows that they haven't gotten the other two.

Here is the code that I have so far:

#include<iostream>
#include<Windows.h>
#include<time.h>
#include <conio.h>
#include<fstream>


using namespace std;

int get_digit();
void goto_xy(int col, int row);
void hide_ans(int line);
void display_question_marks(int r);  // r --> rows, t --- number of tries



int main()
{
	srand(time(0));
	

	int answer[4], col, guess[4] = {0}, i, rows = 17, tries = 1,Number,num;
	
	


	hide_ans(rows);					
	//	system("COLOR 02");

	display_question_marks(rows);

	col = 20;
	while(tries <= 7)
	{
		for(i = 0; i <4; i++)
		{
			goto_xy(col, rows);
			cin >> guess[i];
			col = col + 5;
		}
		
		
		col = 20;
		rows = rows - 2;
		tries = tries + 1;
		display_question_marks(rows);

	}

		

	
	cout<<"The answer is : "<<endl;	
		
	system("pause");
	
	return 0;
}



void goto_xy(int c, int r)	// Function moves cursor to correct column and row (screen)
{ 

    COORD coord;
    coord.X = c;
    coord.Y = r;
				//Use a built-in function that will use the "coord" coordinates and place the cursor
				// at the requird location on the screen.

     SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord); 

     return;
}
	
int get_digit()				// generates random digits 1 - 9
{
	int num;

	num = rand() % 8 + 1;

	return(num);
}


void hide_ans(int line)			// display title, hides the answer
{								// prints row numnbers  line --> rows
	int col, i, ro;

	col = 20;
	ro = 3;

	goto_xy(25, 0);
	cout << "**Master Mind**\n";
	cout<<"         Guess the correct number sequence to win!"<<endl;
	

	
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 3); //replace the number with a number for the color you want
	for (i = 0; i < 4; i++)
	{
		goto_xy(col, ro);
		cout << (char)219;
		col = col + 5;
	}

	for(i = 1; i <= 7; i++)			// prints number of attempts
	{
		goto_xy(15, line);
		cout << i;
		line = line - 2;
	}
	
	return;
}
void display_question_marks(int r) 
{
	int col, i, ro,guess;
		
	col = 15;
	ro = 17;
	
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 4); //replace the 0 with a number for the color you want
	col = col + 5;

	for(i = 0; i < 4; i++)		// prints questions marks on current attempt
	{
		goto_xy(col, r);
		cout << "?";
		col = col + 5;

	}
	
		
	return;

	
}

Hi there,

In pseudocode:

string output = "";

looping through all values of answer[4]
   if answer[n] == guess[n] then output += "*"
   else output += "-"

show output to screen

Sorry, I'd rather make you think about it than give you the solution.

Do let us know if you require further help.

All the best,

I have written :

if ((answer[i]==guess[i]))
	{
		cout<<"*"<<guess[i]<<endl;
	}
	else  ((guess[i]+='-'));
	{
		}

It slightly works but it displays numbers at the end and doesn't really count how many are right :/. Anyway to fix this?

Hi there,

Getting there, very good attempt, here's some corrections:

if (answer[i]==guess[i])  //double parenthesis are not necessary in this case
	{
		cout<<"*"<<guess[i]<<endl;  //there's you're number output
	}
         /* in a regular else you don't provide an expression, it simply means
          * "code to do when above if is not true"
	else
	{
		guess[i] = '-';  //so the code to execute should go here.
        } */

If you want to count how many of the answer were right, you would declare a variable that is incremented by one when answer[i]==guess[i] .

Hope that makes sense to you?

All the best,
