Give me some suggest please!

Write a program to simulate the battle ship game.
You have a 10x10 area and three battle ships are randomly
located.
Each ship occupies 5 consecutive elements and it can have
different orientations.
The player is allow to make 3 hits, by inputting the (x,y)
coordinate. The program will notify the player his score at
the end of the game.
Your program must save the 10x10 map into a file. In the file
Use o to represent element of a battle ship and x to mark
location hitted by the player

my teacher asked me to use
srand(time(0))
this function
i have tried,
but I don't know how to continue...
Can anyone gives me some suggestion how I can do? Thx!~

srand() sets the start point for generating random numbers.
rand() generates a random number.
time() gets the system time.

The reason srand() is called using time() as the [araemter a lot is to produce a new number on each call so that the numbers remain random each time the program is run.

Syntax
time_t time( time_t *timer );

Code:

---

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

int main(void)
{
  int i;

  /* Seed the random-number generator with current time so that
    * the numbers will be different every time we run.
    */
  srand( (unsigned)time( NULL ) );

  /* Display 10 numbers. */
  for( i = 0;  i < 10;i++ )
      printf( "  %6d\n", rand() );
}
