    Exclamation Help with guessing game im making

    Im making a guessing game in c++. THis is my first attempt at a program. I cant figure out how to do it. Heres my code, i dont know whats wrong:

    #include <iostream.h>
    int main ()
    {
    int guess;
    int num;
    cout<<"Enter a guess";
    cin>>guess;
    if(guess = num)
    {
    cout>>"You guessed the right number!";
    }
    else
    {
    cout>>"Try again"
    }
    }

    hmmm

    try to give to the GUESS
    something
    some number

    becouse the GUESS can be -34343434
    and you never guess it

    also use == instead of =.
    and also << istead of >> for cout on the last one...
    so:

    #include <iostream.h>
    int main ()
    {
    int guess;
    int num=4; //or any other number
    cout<<"Enter a guess";
    cin>>guess;
    if(guess == num)
    {
    cout << "You guessed the right number!";
    }
    else
    {
    cout << "Try again" ;
    }
    }

    yipyep!

    the num should have a value as godlike said.
    e.g. int num=33;

    Aslo the equlity sign is ==
    if(guess==num)


    and you should return a value to main.

    You should use the rand() function too I think thats what it is. Ti create a random number. Use like rand()%100 to get a number less the 100.

    Code:
     also use == instead of =. 
    and also << istead of >> for cout on the last one... 
    so: 
    
    #include <iostream.h> 
    int main () 
    { 
    int guess; 
    int num; //or any other number 
    num=rand()%100;//creates a random number between 1 -99
    cout<<"Enter a guess"; 
    cin>>guess; 
    if(guess == num) 
    { 
    cout << "You guessed the right number!"; 
    } 
    else 
    { 
    cout << "Try again" ; 
    } 
    }

    Exclamation I have one more question...

    It exits the program too fast when i run it. I cant see weather or not the guess was right. Is there some way to make it pause untill the user hits a key, like the SLEEP command in QBasic.

    Code:
    #include <windows.h>
    ..
    Sleep(x); // where X is the number of milliseconds to pause the program for

    There are many ways to make a pause before exiting a program.
    You can include <conio.h> and then use
    Code:
     while (!kbhit());
    or <stdio.h> and getchar();
    In DOS you can use sleep(int number_of_seconds); or delay(int number_of_miliseconds); (maybe this will work also under another OS, but probably not good..)

    you could also try adding maybe 3 tries before it tells you the answer, because its kinda illogical to be guessing millions of times for one number. and if you make the limit, say, one hundred and negative one hundred, check if the number that the user inputs is larger or smaller than the limit. just some more things to gain more experience .

    why so many include stuff?

    Why do i have to include all this stuff? How am i suposed to know which to include in my programs? What do they do? Are they like libraries are in qbasic?

    Yes, the header files are like libraries in qbasic. They enable you not to have to worry about codeing some of the everyday routine things such as writing to the screen and getting input and checking to see if a key is hit, ect. You will learn what each header file offers you by experience. By the way you can also open those files and read through them, which will give you the best understanding of what they offer.

    If you're learning C++, forget everything you ever learned about BASIC. If you keep comparing stuff, it doubles your learning time. You have to include all that stuff because it's the code for what you're doing. When using higher level languages like C, the goal is to not write code if someone already has.

    Also, it'll help you get a better answer next time if you specify what is going wrong with the problem. You don't have to know the source, just say what ou don't like about that. And no, it couldn't be -34343434. It's an int - ints don't have that range. It all comes down to what is in the binary code of the memory location that was next. It's not a random number (however unpredictable it may be)

    ok, need help with multiple tries

    What I want is to have 3 tries and then have it ask if the user wants to try again. How do I do this? Heres the code I have now:

    #include <iostream.h>
    #include <windows.h>

    int main ()
    {
    int guess;
    int num=4; //or any other number

    cout<<"Enter a guess: ";
    cin>>guess;

    if(guess == num)
    {
    cout << "You guessed the right number!";
    Sleep(1000);
    }
    else
    {
    cout << "Try again" ;
    Sleep(1000);
    }
    }

    Code:
    #include <iostream.h> 
    #include <windows.h> 
    
    int main () 
    { 
    int guess; 
    int trys=1;
    int num=4; //or any other number 
    
    cout<<"Enter a guess number " << trys << ": "; 
    cin>>guess; 
    cin.ignore(80,'\n'); // i uselly need that
    
    while(trys <=4) {// 4 tries
    if(guess == num) 
    { 
    cout << "You guessed the right number!"; 
    Sleep(1000); 
    return 0;
    } 
    else 
    { 
    cout << "Try again" ; 
    Sleep(1000); 
    } 
    
    }
    cout << " Sorry, but you faild!!!" << endl << "The number was " << num << endl;
    cin.get();
    return 0;
    }
    should work maybe a typo here or there, im to lazy to compile
