Array

[Futbol]

I've been working on a project for 3 hours now and I've got this random guessing game to work flawlessly but i'm having a hard time creating an array that can keep track of the number of guesses a person takes before getting the random number right. I am completely lost. Here is my code so far.

  #include <iostream>
#include <stdint.h>
#include <time.h>
#include <fstream>
using namespace std;
char choice;
int isecret;
void describe_program()
{
	cout << "The object of this game is to guess the random number that's in-between 1 and   100 in as few attempts as possible. ";
	cout << "If you guess the number right you win the   game, if not you can try until you get it right. ";
}
void PlayGame()
{
	int guess;
	switch (choice)
	{
	case 'Y':
	case 'y':
	{
		cout << isecret << endl;
		cout << "Enter a guess between 1 and 100\n";
		cin >> guess;
		
		do
		{
			if (guess < isecret)
			{
				cout << "Your guess is too low\n";
				cout << "Try and guess again\n";
				cin >> guess;
			}

			else if (guess>isecret)
			{
				cout << "Your guess is too high" << endl;
				cout << "Try and guess again" << endl;
				cin >> guess;
			}
			if (guess == isecret)
			{
				cout << "Congradulations, you guess the number right\n";
			}
		} while (guess != isecret);
		break;

	}
	case 'N':
	case 'n':
	{
		return;
	}
	}
}
int main()
{
	describe_program();
	cout << "If you want to play the game   enter 'Y' if not enter 'N' to exist." << endl;
	cin >> choice;
	srand(time(0));
	isecret = rand() % 100 + 1;
	while (choice != 'N' && choice != 'n')
	{
		isecret = rand() % 100 + 1;
		PlayGame();
		cout << "Do you want to play the game again" << endl;
		cin >> choice;
	}
	return(0);

}

Why do you need an array? Just create a normal variable.

int nrOfGuesses = 0;

And each guess, you can do

nrOfGuesses++; this is like nrOfGuesses = nrOfGuesses + 1;
So basically, you increase nrOfGuesses each time they guess. Its that simple mate :)

Wish my teacher made it that simple, but i have to use the array because i have to keep track of the users average for each game played and then finally display it when they decided to exist the game, i have to show them the number of guesses for each individual game at the end of the program, not after each game they finish. hope that makes sense.

Okay so, I made some improvements and implemented what you wanted. Read the comments. Take a look -

void describe_program()
{
	cout << "The object of this game is to guess the random number that's in-between 1 and   100 in as few attempts as possible. ";
	cout << "If you guess the number right you win the   game, if not you can try until you get it right. ";
}

void PlayGame(int* nog, int i, int isecret) // nog is the array. 
{

	// Im not sure why you had a switch statement in here.
	int guess;

	cout << isecret << endl;
	cout << "Enter a guess between 1 and 100\n";

	do
	{
		
		cin >> guess;
		
		if (guess < isecret)
		{
			cout << "Your guess is too low\n";
			cout << "Try and guess again\n";
			nog[i] = nog[i] + 1; // increase amount of guess each guess.
		}

		else if (guess > isecret)
		{
			cout << "Your guess is too high" << endl;
			cout << "Try and guess again" << endl;
			nog[i] = nog[i] + 1; // increase amount of guess each guess.
		}

		else
		{
			cout << "Congradulations, you guess the number right\n";
		}

	} while (guess != isecret);

	
}
int main()
{
	char choice; // Dont use global variables. Create them in main.
	int isecret = 0; // read above.
	int nog[20] = {}; // creates an array.
	int i = 0; //This is the amount of rounds played.
	describe_program();
	cout << "If you want to play the game   enter 'Y' if not enter 'N' to exist." << endl;
	cin >> choice;
	srand(time(0));
	while (choice != 'N' && choice != 'n')
	{
		isecret = rand() % 100 + 1;
		PlayGame(nog, i, isecret);
		i++; // increases amount of rounds each round.
		cout << "Do you want to play the game again" << endl;
		cin >> choice;
	}

	cout << endl << nog[0] << endl << nog[1] << endl; 
	// This cout statement is just to show that you can print out the amount of guesses
	// each round.  If you play 3 rounds. The amount of guesses will be stored in
	// nog[0], nog[1] and nog[2].
	return(0);
}

Thank you so much for your help. This is exactly what he wants us to do except for a few problems with the code above. This would work if I was suppose to limit the amount of games a user plays, but since I'm not suppose to, according to this code above I would have to display all 20 elements in the array since I will never know how many times the user plays the game. I was thinking of using a counter in the array and increasing it as the user keeps playing, that way it prints out only for the amount of games the user plays. I got this far but i'm not sure how to actually print it out.

#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;
int asize = 0;
int nog[20];
int isecret;
int i = 1;
int total = 0;
char play = 'g';
void describe_program()
{
	cout << "The object of this game is to guess the random number that's in-between 1 and   100 in as few attempts as possible. ";
	cout << "If you guess the number right you win the   game, if not you can try until you get it right. ";
}
void PlayGame()  
{
	int guess;
	cout << isecret << endl;
	cout << "Enter a guess between 1 and 100\n";

	do
	{

		cin >> guess;
		i++;

		if (guess < isecret)
		{
			cout << "Your guess is too low\n";
			cout << "Try and guess again\n";
		}

		else if (guess > isecret)
		{
			cout << "Your guess is too high" << endl;
			cout << "Try and guess again" << endl;
		}

		else
		{
			cout << "Congradulations, you guess the number right\n";
			nog[asize] = i;
		}
		asize++;
	} while (guess != isecret);


}
int main()
{
	char choice;
	describe_program();
	cout << "If you want to play the game   enter 'Y' if not enter 'N' to exist." << endl;
	cin >> choice;
	srand(time(0));
	while (play == 'g')
	{
		if (choice == 'Y' || choice == 'y')
		{
			isecret = rand() % 100 + 1;
			PlayGame();
			cout << "Do you want to play the game again" << endl;
			cin >> choice;
		}
		else if (choice == 'n' || choice == 'N') 
		 break;
		else
			cout << "Invalid choice";
		break;


	}

Using your code, I can only play the game once, if I type in Y or y it still exists after one round.

Edit: Also, Im not sure if this is coming from your professor, but if he or she is letting you use global variables... jeez. Seriously stop using global variables.
