Question

Make the following for a battleship game (I need to write the program for it, need a basis):

1.       Data structure definitions (in battleship.h file):

a. Playing board

b. Ship

c. Any other needed constants/enums/typedefs

2. Commented function prototypes (in battleship.h file):

a. Initialize board (InitializeBoard)

b. Display board (DisplayBoard)

c. Initialize all ships (InitializeAllShips)

d. Initialize individual ship (InitializeShip)

e. Place ship on board (PlaceShip)

f. Check requested position is valid for a ship (IsValidPosition)

3.       Pseudocode for a main() function that uses the above functions to:

a. Create/initialize a playing field

b. Test that a given ship can be placed in all valid positions

Explanation / Answer

Program plan: Here i wrote the code in c programming language and mentioned the proper comments to understand the code.

Program:

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

//Iniialize board method definition here we are initialising the board
void initilizeBoard(int b[][5])
{
    int l, c;
for(l=0 ; l< 5 ; l++ )
     for(c=0 ; c< 5 ; c++ )
  b[l][c]=-1;
}
//display method definition for displaying the ~,*,X
void displayBoard(int b[][5])
{

    int l, c;

printf(" 1 2 3 4 5");
printf(" ");

for(l=0 ; l< 5 ; l++ ){
     printf("%d",l+1);
     for(c=0 ; c < 5 ; c++ ){
  if(b[l][c]==-1){
      printf(" ~");
  }else if(b[l][c]==0){
      printf(" *");
  }else if(b[l][c]==1){
      printf(" X");
  }

     }
     printf(" ");
}

    }
//definition of initializeship method
void initilizeShips(int ships[][2])
{

int s,l;

for(s=0 ; s < 3 ; s++){
     ships[s][0]= rand()%5;
     ships[s][1]= rand()%5;

     //let's check if this shot was not tried
     //if it was, just get out of the 'do while' loop when draws a pair that was not tried
     for(l=0 ; l < s ; l++){
  if( (ships[s][0] == ships[l][0])&&(ships[s][1] == ships[l][1]) )
      do{
   ships[s][0]= rand()%5;
   ships[s][1]= rand()%5;
      }while( (ships[s][0] == ships[l][0])&&(ships[s][1] == ships[l][1]) );
     }

}
    }
//definition of giveshot method read the user input
void giveShot(int shot[2])
{

printf("Line: ");
scanf("%d",&shot[0]);
shot[0]--;

printf("Column: ");
scanf("%d",&shot[1]);
shot[1]--;

}
//definition of hitshot method compares the user shot with random initialized ship values
int hitship(int shot[2], int ships[][2])
{
    int s;

for(s=0 ; s < 3 ; s++){
     if( shot[0]==ships[s][0] && shot[1]==ships[s][1]){
  printf("You hit a ship with the shot (%d,%d) ",shot[0]+1,shot[1]+1);
  return 1;
     }
}
return 0;
    }
//tip method provides the tip for the user about the hit information
void tip(int shot[2], int ships[][2], int a)
{
int l=0,c=0,row;

//count how many ships there is line/column
for(row=0 ; row < 3 ; row++){
     if(ships[row][0]==shot[0])
  l++;
     if(ships[row][1]==shot[1])
  c++;
}

printf(" %d: line %d -> %d ships column %d -> %d ships ",a,shot[0]+1,l,shot[1]+1,c);
}
//to change the board
void changeBoard(int shot[2], int ships[][2], int board[][5]){
if(hitship(shot,ships))
     board[shot[0]][shot[1]]=1;
else
     board[shot[0]][shot[1]]=0;
    }

int main() {
int board[5][5];
int ships[3][2];
int shot[2];
int attempts=0,
     hits=0;
//calling the start board function
initializeBoard(board);
initilizeShips(ships);

printf(" ");
//do..while loop to run the game and runs until 3 shots given

do{
     displayBoard(board);
     giveShot(shot);
     attempts++;

     if(hitship(shot,ships)){
  tip(shot,ships,attempts);
  hits++;
     }
     else
  tip(shot,ships,attempts);

     changeBoard(shot,ships,board);

}while(hits!=3);

printf(" Finished game. You hit the three ships in %d attempts", attempts);
displayBoard(board);
    }
