C++ Tutorials - Absolute n00b spoonfeed

so i have this project that i have to make a game like the number guessing one with the difference that i put the number and the computer tries to guess. I have wrote most of it but my only problem is that i cant put limits into the computers guesses...take a look and any suggestion is usefull

Code: Select all

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main()
{
    int theNumber;
    int cmpGuess;
    char highLow;
   
   
    cout << "Enter your number from 1-100";
    cin >>theNumber;
   
    srand(time(0));
    cmpGuess = rand()%100+1;
   
    do
    {
      cout << "i guess its "<<cmpGuess<<"...is it higher or lower than that?(h/l)";
      cin >> highLow;
             if (highLow == 'l')
             {
                                    cmpGuess=rand()%cmpGuess+1;
                           
             }
          cout << endl;
             if (highLow == 'h')
             {
                                   cmpGuess=cmpGuess+rand()%(100-cmpGuess) +1;               
             }
          cout << endl;
    }
    while (cmpGuess!=theNumber);
   
   
    system ("PAUSE>>NULL");
   
    return 0;
}         


Hah, never thought someone will put the computer to guess xD

And I don't think that computers are made for that, but it looks like one of those questions that need several head smashing in the wall to get over it.

Just so to make the game look more ... realistic. The computer knows what the number typed in is, so you can do the "higher" and "lower" with if statements, and adjust it every time the computer picks a random number. Hmm, I somehow forgot what I was talking about )

So, yes, that's a good idea, it just seems so ... FATAL CRASH.

Later Edit:
Uh, what's that "PAUSE<<NULL" in system() function? Never saw that before. It works fine with just "PAUSE" ... no?

And another edit:
Sorry, wasan't paying attention to the main question, that 'computer guessing' kind of bluescreened me.
You could make an integer (int nCount = 0) and at the end of the while loop increse it, then put inside
while ( (cmpGuess!=theNumber) && (nCount < 5));

Hope this helps somewhat.

thanks it helps alot

I wrote one of those before but mine was done in a split second
I just had my rand range get reassigned to what number was guessed if it wasn't right
all I did is type in a number and let the computer do the rest

how do u set a rand range ? thats what i m looking for

You could make a funtion that return a random number between two numbers you want.

Wait, know that I think of it, it's hard to do. Bluescreend again.

Here's a link about the random numbers, you could implement it random-number-generator-t18.html

Code: Select all

number = rand() % 100 + 1;


the first number 100 is how many random numbers you have the 1 makes it so you have a range from 1 - 100 and not 0 - 99
so the 1 would be your low range

here was the code I did for mine you can use it to help understand what I'm saying

Code: Select all

#include <iostream>
#include <limits>
#include <ctime>

using std::cout;
using std::cin;

int main()
{   
   srand((unsigned)time(NULL));
   
   int number;
   int guess;
   int counter = 1;
   int newmod;
   int newlow = 0;
   int newhigh = 100;

   while ((cout<< "Enter a number between 1 and 100\n\n") &&!(cin>> number) || (number > 100 || number <= 0))
   {
      cout<< "Please enter a number between 1 & 100 nothing else\n\n";
      cin.clear();
      cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
   }
   
   guess = rand() % newhigh + newlow;
do
{
   if (guess > number)
   {
      cout<< guess << "\t<<<< To high\n";
      ++counter;
      newhigh = guess;
      newmod = newhigh - newlow;
      ++newmod;
      guess = rand() % newmod + newlow;
   }
      else if (guess < number)
      {
         cout<< guess <<"\t>>>> Too low\n";
         
         ++counter;
         newlow = guess;
         newmod = newhigh - newlow;
         ++newmod;
         guess = rand() % newmod + newlow;
      }
}while (guess != number);

      cout<< "You win with " << counter << " guess the number you guessed was " << number <<"\n\n";
}


tnaks guys .got it
