Thread: Input from keyboard

Hey,

I'm trying to write a simple game (battleships) in C and am a little stuck. The information i've found on the internet and in books hasn't helped me a great deal so i turn to you!

This is my code so far:

Code:

#include <stdio.h>
#include <8051.h>

void putchar(char c);
int c;
int hits;
int array_pointer;
int Battleship[5][5] = { {'0','0','1','1','1'}, {'1','0','0','0','0'}, {'1','0','1','1','0'}, {'0','0','0','0','0'}, {'1','1','1','1','1'}}; 

void main()
{
	putchar;
	printf("\x1b[2J",0);						//Clears terminal screen
	printf("%s\n\r",&"___________________________");		//Prints title block
	printf("%s\n\r",&"---B-A-T-T-L-E-S-H-I-P-S---");		//Prints title block
	printf("%s\n\n\n\n\r",&"___________________________");		//Prints title block
	printf("%s\n\n\n\r",&"Press ENTER to begin...");		//Prints title block
	
	printf("%s %s %s %s %s\n\r", "X", "X", "X", "X", "X");
	printf("%s %s %s %s %s\n\r", "X", "X", "X", "X", "X");
	printf("%s %s %s %s %s\n\r", "X", "X", "X", "X", "X");
	printf("%s %s %s %s %s\n\r", "X", "X", "X", "X", "X");
	printf("%s %s %s %s %s\n\r", "X", "X", "X", "X", "X");
	}

void game()
{
	hits = 12;
	array_pointer = 0;


}
void putchar(char c)
{
	while(! TI);
	TI = 0;
	SBUF =c;
}

I'm hoping to get the user to press enter to begin the game, where the grid of 'X' will apear, and where any other key does nothing.

PLEASE HELP!

- putchar is a standard-lib function, NEVER override this
- global vars are bad
- \n\r are wrong, simple use \n
- &"" is wrong, string literals are defined without &
- many other beginners stuff ...

Code:

#include <stdio.h>

int readChar() {
  char in[2];
  if( fgets( in, 2, stdin) ) return *in;
  return EOF;
}


#define NUMSHIPS 5
int c;
int hits;
int array_pointer;

void game()
{
	hits = 12;
	array_pointer = 0;
}
int main()
{
  char Battleship[NUMSHIPS][5] = { {' ',' ','X','X','X'}, {'X',' ',' ',' ',' '}, {'X',' ','X','X',' '}, {' ',' ',' ',' ',' '}, {'X','X','X','X','X'}}; 
  int i;
  printf("\x1b[2J",0);						//Clears terminal screen
  printf("%s\n","___________________________");		//Prints title block
  printf("%s\n","---B-A-T-T-L-E-S-H-I-P-S---");		//Prints title block
  printf("%s\n\n\n\n","___________________________");		//Prints title block
  printf("%s\n\n\n","Press ENTER to begin...");		//Prints title block

  readChar();

  for( i=0; i<NUMSHIPS; ++i )
    printf("%c %c %c %c %c\n", Battleship[i][0],Battleship[i][1],Battleship[i][2],Battleship[i][3],Battleship[i][4]);

  return 0;
}
