Lesson 2: Variables, Cycles, Conditions...

Exercise 1:

Now you are going to make your first game! The task is to guess number. Player can try to the find the correct number 8 times. This is how the game should look like:

Generating new number... done.
Insert a number: 23
Too high!
Insert a number: 12
Too low!
Insert a number: 20
Too high!
Insert a number: 18
You win!

A bit of tip: This little software is able to generate a random number between 0 and 100:

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

int
main (void)
{
  int numb;

  srand (time (NULL));
  numb = rand () % 100;

  printf ("%d\n", numb);
  return 0;
}

Exercise 2:

We are member of the "important free software" audio player community. We have decided to change a progress bar so everybody must propose a new one with a little C source code. The progress bar should look like this:

[ |-------------------------------->     | sec: 121 of 250 ]

The software must show an animated progress bar. You can use "usleep (300000);" to stop the execution of your software for 1/3 of second (without usleep your software will be too fast). The best progress bar will be integrated into our "important free software player".

----
#include <unistd.h>
#include <stdio.h>

int
main (void)
{
  printf ("Hello\n");
  usleep (300000);
  printf ("World\n");
  return 0;
}
