First program. Need help.

I know this is one of the simplest programs ever, but I need help because I'm new to C++.

Code:

---

#include <iostream.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
        int num;
        int inputnum;
        num = rand()%101;
        cout<<"Pick a number between 0-100"<<endl;
        cin>>inputnum;
        if(inputnum == num)
        {
                cout<<"Your right! The number is "<<num<<endl;
        }
        while(inputnum > num)
        {
                cout<<"Try a little lower"<<endl;
                cin>>inputnum;
        }
        while(inputnum < num)
        {
                cout<<"That's too low."<<endl;
                cin>>inputnum;
        }
        return 0;
}

1st problem: it picks 1 number then it's the same all the time
2nd problem: after 3 guesses it closes

the compiler I'm using is VC++

You need to seed the rand function.
See here for details

Ok thanks, now I have another question since it's now finished and I want to modify it. How would you have a high score stored?

Look up fstream. It lets you read/write from/to files.

Also, #include <time.h> and call:


srand((unsigned) time (NULL));

to randomize the rand() every time.

Do you mean number of guesses? Keep track of them in a variable like count, after the number is guessed set another variable like highScore = count. On subsequent loops compare count to highScore, reset it if higher.
You might want to look at the logic flow in your program. I think it'll only work in some situations. Compare all values using if statements in a while loop. It closes after three guesses because you're not doing that. Run through it on paper and see.

here's my current code:

Code:

---

#include <iostream.h>
#include <stdlib.h>
#include <time.h>
#include <conio.h>
int rand(void);

int main()
{
        int num;
        int inputnum;
        srand(time(NULL));
        num = rand()%101;
        cout<<"Pick a number between 0-100"<<endl;
        cin>>inputnum;
        bool loop = true;       
        while( loop )       
        {
                if(inputnum == num)
                {
                        cout<<"Your right! The number is "<<num<<endl;
                        getch();
                        return 0;
                }
                while(inputnum > num)
                {
                        cout<<"Try a little lower"<<endl;
                        cin>>inputnum;
                }
                while(inputnum < num)
                {
                        cout<<"That's too low."<<endl;
                        cin>>inputnum;
                }
        }
        return 0;
}

Where would I store a high score, and if it's in a file, couldn't someone easily edit it?

hide it within a bunch of numbers or somthing clever like that

And it's "you're", not "your".
