ok so I am using this code below to figure out how to get the computer to guess a random 5 digit number and the player has to put in there own number and i got to let them know if they got any correct numbers and if they got any correct numbers in the right spot. i got the game loop implemented and i got it working all the way up until the telling them how many they got right this is where i am super confused can someone please guide me in the right direction

 
#include "stdafx.h"
#include <iostream>
#include <ctime>
#include <cstdlib>
#include <string>

using namespace std;

int main()
{
	int size = 5;
	int range = 9;
	char lowest = '0';
	string guess;
	int number;
	int correct;
	int position;
	bool gameover = false;

	srand(time(0));

	string answer = "";
	for (int i = 0; i < size; i++)
	{
		char ch = lowest + rand() % range;
		answer += ch;
	}


	number = 1;
	correct = 0;
	position = 0;

	while (!gameover)
	{
		cout << "Guess #" << number << ": Enter 5 numbers that are '0' through '9': ";
		cout << answer;
		cout << "\n";
		cin >> guess;

		if (guess == answer)
		{
			cout << "Right!  It took you " << number << " move";
			if (number != 1) cout << "s";
			cout << "." << endl;
			gameover = true;
			
		}
		
		for (int i = 0; i < 5; i++){
			if (guess[i] == answer[i]){
				correct = ;

			}
			
		}

		while (position < size)
		{
			if (size == position) correct++;
			position++;
		}
		number++;


		cout << "Correct position: " << position << endl;
		cout << "Correct letter:   " << correct << endl;


	}

	
	cout << "GAME OVER\n\n";

	system("pause");
	return 0;
}

You could do something like:

int const max = 99999;
int const min = 10000;

int answer = rand() % (max - min + 1) + min;

int attempt = 1;
int guess = 0;
while(guess != answer)
{
    std::cout << "Guess attempt #" << attempt << std::endl;
    do
    {
        std::cout << "Please enter a guess(" << min << '-' << max << "): ";
        if(!cin) //error with input
        {
            std::cin.clear();
            std::cin.ignore(1024, '\n'); //or use std::numeric_limit
        } //edited to add this forgot last time
    } while(!(std::cin >> guess) || guess < min || guess > max);

    ++attempt;
}

std::cout << "Congrats you guessed the number in " << attempt << " guesses!" << std::endl;

But my issue is telling hte person how many numebrs of the 5 digit number they guessed is actually correct

say the number is 56478

and u guessed 423568

i have to be able to tell u that 3 numbers that u guessed is in the number and 1 number is in the right spot

[giblit]

oh sorry I missed that part. You're going to have to iterate through both of them and keep track with two flag variables. Or you could use the .find function

[adiktid]

Ahh the find function, I am new to iterators and have only used them for vectors. so I can use them for strings as well?

I have to make it like this

Have your computer generate a random 5 digit number, as a string. Then the user must guess the number. Using the code:

1 = implies right Number, Right Place.
2 = implies right Number, Wrong Place.
0 = implies Wrong Number.

So the computer decides on 12345; the user guesses 11235; the computer should respond with 10221. Hint: Watch out for a double number like 11 when there is only one.

I have this as the code

#include "stdafx.h"
#include <iostream>
#include <ctime>
#include <cstdlib>
#include <string>
using namespace std;


struct fields{
	int size = 5;;
	int range = 9;
	char lowest = '0';
	string guess;
	string answer;
	int number;
	int correct;
	int position;
	bool gameover = false;

};

void gameplay(fields & info);

int main()
{
	fields game;

	gameplay(game);

	

	system("pause");
	return 0;
}

void gameplay(fields & info){

	srand(time(0));
	

	info.answer = "";
	for (int i = 0; i < info.size; i++)
	{
		char ch = info.lowest + rand() % info.range;
		info.answer += ch;
	}


	info.number = 1;
	info.correct = 0;
	info.position = 0;

	while (!info.gameover)
	{
		cout << "Guess #" << info.number << ": Enter 5 numbers that are '0' through '9': ";
		cout << info.answer;
		cout << "\n";
		cin >> info.guess;

		if (info.guess == info.answer)
		{
			cout << "Right!  It took you " << info.number << " move";
			if (info.number != 1) cout << "s";
			cout << "." << endl;
			info.gameover = true;

		}

		
		int correctNumbers = 0;
		
		for (char const &ch : info.guess) //iterate over string you can do anyway you want
		{
			if (info.answer.find(ch) != string::npos)
			{
				++correctNumbers;
			}
		}

		int const digits = 5;
		int correctPositions = 0;
		
		int correctPosition[digits];
		int test = 0;

		
			for (int i = 0; i < digits; ++i)
			{
				if (info.answer[i] == info.guess[i])
				{
					++correctPositions;
				}
				if (info.answer[i] == info.guess[i]){

					correctPosition[i] = 2;
					cout << correctPosition[i];
				}
				

				
			}
		

		while (info.position < info.size)
		{
			if (info.size == info.position) info.correct++;
			info.position++;
		}
		info.number++;


		cout << "\nCorrect position: " << correctPositions << endl;
		cout << "Correct letter:   " << correctNumbers << endl;
		


	}


	cout << "GAME OVER\n\n";
}

I go tit where it puts a 2 if it is the right number in the right place and a 0 if the number is not part of it,,h i cant figure out how to include the 1 though can i please get some help
