Random number generation

I am trying to write a piece of code using a random number generation result. I have not been able to successfully debug (see below). Could you assist? I am very new to this programming language.

// Guess - Number Game
#include <iostream>

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

#include <cstdlib>

int main()
{

int guessCounter = 1,
x;


for (int guess = 1; guess <=20; guess++) {
x = 1 + rand() % 1;

cout <<"I've got the number. Please guess it:";
cin >> guess;


if (guess < x)
cout << "It's less than the number. Please guess again:";

if (guess > x)
cout << "It's greater than the number. Please guess again:";
else
break;
guessCounter = guessCounter+ 1;
cout<<"Input next guess.";

if (guess == x)
cout << "You guessed it!"<<endl;

}
return 0;

}

You made this way too complex. First off, it doesnt do it quite corectly. I runs it 20 times regardless if the guess it right or not. Here, I wil hep you by giving you some usefull code. It may not all be correct in the random part, because i am not changing that. What compiler are you using?

Code:

#include <iostream> 
#include <cstdlib>

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

int main() 
{ 

int guessCounter = 0;
int x = 1 + rand() % 1; 

cout <<"I've got the number. Please guess it:";

while (guess != x)
{
cin >> guess; 

if (guess < x) 
cout << "It's less than the number. Please guess again:"; 

if (guess > x) 
cout << "It's greater than the number. Please guess again:"; 

if (guess == x) 
cout << "You guessed it!"<<endl;

guessCounter = guessCounter+ 1; 

cout<<"Input next guess.";
}
return 0; 
}

Code:

// Guess - Number Game 
#include <iostream> 
#include <cstdlib>
#include <ctime>

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

int main() 
{ 
    int guessCounter, x, guess;

    // Only get a single random number, otherwise you are getting
    // a new one each time you go through the loop.  Also, you need
    // to seed the random number generator otherwise you get the
    // same "random" number each time you run the program.  Last,
    // what you had will only give 1 as the number, try picking something
    // larger to do the "%" with, for example, this will give a number
    // from 1 to 100.

    srand( time(NULL) );
    x = 1 + rand() % 100;
    cout <<"I've got the number. Please guess it:"; 

    for( guessCounter = 0; guessCounter < 20; guessCounter++ )
    { 
        cin >> guess; 

        if (guess < x) 
            cout << "Your guess is less than the number. Please guess again:"; 

        else if (guess > x) 
            cout << "Your guess is greater than the number. Please guess again:";
        else if (guess == x) 
        {
            cout << "You guessed it!"<<endl; 
            break;
        }
    } 

    return 0; 

}

Try this:

PHP Code:

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

using namespace std;

int main() 
{ 
    
    int guessCounter = 1, 
    int x = 0; 
    int guess = 0;

    srand( time(NULL) );


    x = 1 + rand() % 1; // will give you a random number from 1 to 2 (?)
    
    cout <<"I've got the number. Please guess it:"; 
    

    for( guessCounter = 0; guessCounter < 20; guessCounter++ )
    { 
        cin >> guess; 


        if (guess < x) 
        {
            cout << "It's less than the number. Please guess again:"; 
        }
        else if (guess > x) 
        {
            cout << "It's greater than the number. Please guess again:"; 
        }
        else
        {
            // if it's neither < nor >, it should be ==
            break;
        }            

        cout<<"Input next guess."; 
    }

    if (guess == x) 
    {
        cout << "You guessed it!"<<endl; 
    }
    else
    {
        cout << "You lost. It was " << x << endl;

    } 
    
    return 0; 
} 


yeah, what nvoigt put would work, but you'll only get 19 guesses with that, lol. he meant '<=20' i think. or you can do this:

Code:

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

int main()
{
    int guesses=1;
    int guess=0;
    int x=0;

    srand(TIME(NULL));

    x=1 + rand() % (5-1+1); //in between 1 and 5

    do
    {
        cout<<"Enter your guess: ";
        cin>>guess;

        if(guess>x)
            cout<<"Too high. Guess again."<<endl;
        if(guess<x)
            cout<<"Too low. Guess again."<<endl;
        if(guess==x)
            break;

        guesses++
    }while(guesses<=20);

    if(guesses==21)
        cout<<"You lost"<<endl;
    if(guesses<21)
        cout<<"You won"<<endl;

    return 0;
}
