Thread: Guess the number game

Hey again.

Continuing with my assignment and seem to have come a long way in understanding C. However part of my assignment was to create a guess the number game which randomly generates a number and you simply have to guess it, whist it either tells you if your guess was too high or too low. Now here is my code:

Code:

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

int main(int argc, char *argv[])
{
int secret_number;
int guess=0;
int play=1;
const int LOW=-100;
const int HIGH=100;
time_t seconds;
time(&seconds);
srand((unsigned int) seconds);
while (play==1)
{
      printf("I have stored a random number between -100 and 100, try and see if you can guess the number:\n");
      secret_number=rand()%(HIGH-LOW+1)+LOW;
      while(guess!=secret_number)
      {
          scanf("%d",&guess);
          if(guess==secret_number)
          {
                  printf("\nYour Guess was correct! The number is %d\n", secret_number);
          }
          else if(guess>secret_number)
          {
                  printf("\nGuess was too high, try again\n");
          }
          else
          {
                  printf("Guess was too low, try again\n");
          }
      }
         printf ("\nWould you like to play again? Yes=1 or No=2\n");
         scanf ("%d", &play);
}
 system("pause");
 return;
}

It works fine but I got a bit of help on generating random numbers from the Internet. My main trouble is that I don't think I can actually explain everything that's going on here.
If you were to explain each step in this program, what would you say?

Thank you.

ok cheers guys, I did have the '0' after return, dunno how it got deleted.

I've done some data sort alogorithms and found them easy, but need to re-write this guess the number crap so I can explain it to my tutor.

I usually put lines of explanation under each set of code, but as I don't understand what this code is doing I can't do that!

Code:

guess = !secret_number;

just to make sure they don't match before the game even begins.

I have that line in my While loop! - look!
My god I hate C code, how the hell do you guys enjoy this??

Ok, gotcha. I added the lin of code in to my program and it still works, I'm guess this is a good thing?

I inserted it below my while loop

I managed to make your program hit the fan by typing in a decimal!

Don't type in the decimal then!

It works as long as you don't blow any air on it, so that's good enough for me!
