OK here's an example....

Duh... I have an example of what i'm looking for. This is one that I did in class but i need to change it so that the computer picks the number and the user guesses (oh an Esp. that program didn't work x.x I think it's cuz our compiler is Microsoft Visual C++ 4.0) Anyways... here's the program we did
*Note I need to change it so the computer picks the number*

#include <iostream.h>

void main ()
{
char high_low;
int done = 0, current_guess = 50, highest = 100, lowest = 0;

do{
cout<<"Is "<<current_guess
<<"too high, too low, or is it right? ('h', 'l', 'r')";
cin>>(high_low)

switch (high_low)
{
case 'l':
if (current_guess > lowest);
{
lowest = current_guess;
}
current_guess = current_guess + (highest - current guess) /2;
break;

case 'h':
if (current_guess <highest);
{
highest = current_guess;
}
current_guess = lowest + (current_guess - lowest) /2;
break;
default:
cout<<high_low<<" is not a valid choice \n";
break;
}
}while (!done);
}


Umm... yeah that's about it...but I need it done so that the computer 'thinks' of the number and the person guesses.... anyone that can help me with this?

current_guess = current_guess + (highest - current guess) /2

should read current_guess = current_guess + (highest - current_guess) /2

Also no switch case for reply r.

Other than that (and I think a missing ; somewhere) this compiles fine on DEVC++

As for your other question, if you look back at the replies, it's already been answered.

Easy isn't it.

Take care,

Rob.

Code:

#include <iostream>
#include <ctime>
using namespace std;

int main ( void )
{
  int correct = 0,
      userGuess,
      compAnswer;
  srand ( time ( NULL ) );
  compAnswer = rand() % 100;
  while ( !correct ) {
    cout<<"Care to guess? ";
    cin>>userGuess;
    if ( userGuess > compAnswer )
      cout<< "Too high\n";
    else if ( userGuess < compAnswer )
      cout<<"Too low\n";
    else {
      cout<< userGuess <<" was correct!\n";
      correct = 1;
    }
  }
  return EXIT_SUCCESS;
}

>void main ()
Don't use void main, it's wrong

-Prelude

The microsoft visual isn't accepting <ctime> .... you also put <iostream> but it only takes <iostream.h>... could it be something like that with the ctime error?

>you also put <iostream> but it only takes <iostream.h>
You have an old compiler, the current C++ standard omits the .h extension and adds c to headers that are based from the C language. Simply change

Code:

---

#include <iostream>
#include <ctime>
using namespace std;

---

to

Code:

---

#include <iostream.h>
#include <time.h>

---

-Prelude

If you are using MSVC++ 4.0, then it probably won't recognize ANSI C++. Just use iostream.h and time.h instead.

Code:

---

#include <iostream.h>
#include <time.h>

#define TRUE 1
#define FALSE 0

int main ()
{
  int correct = FALSE,
      userGuess,
      compAnswer;

  srand ( time ( NULL ) );  // Seed rand()
 
  compAnswer = rand() % 100;
 
  while ( !correct )
  {
    cout<<"Care to guess? ";
    cin>>userGuess;
   
    if ( userGuess > compAnswer )
      cout<< "Too high\n";
    else if ( userGuess < compAnswer )
      cout<<"Too low\n";
    else {
      cout<< userGuess <<" was correct!\n";
      correct = TRUE;
    }
  }
  return EXIT_SUCCESS;
}
