Guess the number game

frozened (2)
Hey, i need help with my homework. The assignment is to create a game which generates a number between 1-100 and then you have to guess it, after each guess the computer tells you if the guess is too high or too low. Also you only have 7 guesses, if you fail or succeed in guessing the number the computer must ask you if you want to play again.

{
int number=rand()%100+1;;

y=1;

	while(x!=number)
	{
		if(x>number)
		{
			cout<<"Too high, guess again: ";
			cin>>x;	
                        y++;	
		}
		else if(x<number)
		{

                        y++;
		}
		
    }
	   
	   
	if(x=number)
	{
	  cout<<"gratz, do you want to play again? [y/n]";
	}



}
return 0;
}



I managed to get the basic to work but i need help with ending the task if you have already guessed 7 times and how to ask if you want to play again.

First off
Don't make code using variables whose names are completely irrelevant to their purpose (i.e. int x, int y) when making code, it will just make big projects impossible to understand.

Second off

I tried to put in necessary comments and I changed your variable names, check out if this makes sense or not

Something like this should work (make me know if there are bugs ;) , I have written it on the volley)

    int num = 0,
        random_num = 0;//number the user has to guess
    char answer = 'y';
    int c = 0;//counter variable

    do
    {
        random_num = rand() % 100 + 1;
        do
        {
            std::cout << "Guess a number: ";
            std::cin >> num;

            if(num == random_num) std::cout << "You guessed it!\n";

        c = 0;

Yes, thank you very much for your help, it makes a lot of sense to a beginner like me. I guess i was stuck because we haven't actually studied or even looked at the bool command.
Also thanks for the tip!
