Hi everyone! This is the code that I have written in order to print a tic-tac-toe board. For example, if input was this:
1 2 0
1 1 2
0 2 0
The board would be this:
X . O
X X .
O . O
However, I don't know how to use void instead without changing the behaviour of the program. I have tried adding the following:
void readBoard(int board[SIZE][SIZE]);
void printBoard(int board[SIZE][SIZE]); but I know I have done it wrong
//WITHOUT VOID
int main (int argc, char *argv[]) {
int ROW[3] [3];
int i, j;
printf("Please enter the board:\n");
for (i=0; i<3; i++) {
for (j=0; j<3; j++) {
scanf("%d", &ROW[i] [j]);
}
}
printf("Here is the board:\n\n");
for (i=0; i<3; i++) {
for (j=0; j<3; j++) {
if (ROW[i] [j]==0) {
printf("O ");
}
else if (ROW[i] [j]==1) {
printf("X ");
}
else if (ROW[i] [j]==2) {
printf(". ");
}
if (j==2) {
printf ("\n");
}
}
}
return 0;
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//WITH VOID
#define SIZE 3
void readBoard(int board[SIZE][SIZE]);
void printBoard(int board[SIZE][SIZE]);
int main (int argc, char *argv[]) {
int BOARD[SIZE] [SIZE];
readBoard (BOARD,SIZE);
printBoard (BOARD,SIZE);
return 0;
}
printf("Please enter the board:\n");
void readBoard (int BOARD{] [SIZE], int
int i,j;
for (i=0; i<3; i++) {
for (j=0; j<3; j++) {
scanf("%d", &BOARD[i] [j]);
}
}
printf("Here is the board:\n\n");
for (i=0; i<3; i++) {
for (j=0; j<3; j++) {
if (BOARD[i] [j]==0) {
printf("O ");
}
else if (BOARD[i] [j]==1) {
printf("X ");
}
else if (BOARD[i] [j]==2) {
printf(". ");
}
if (j==2) {
printf ("\n");
}
}
}
//There is a winner if noughts or crosses gets 3 in a row or column, diregard diagonals so 3 in a diagonal is not counted as a win.
int winner(int board[SIZE][SIZE]);
for (i=0; i<3; i++) {
for (j=0; j<3; j++) {
if ((board [0] [0]=X) && (board [0] [1]=X) && (board [0] [2]=X) {
printf("Noughts win\n");
} else if ((board [1] [0]=X) && (board [1] [1]=X) && (board [1] [2]=X) {
printf("Noughts win\n");
} else if ((board [2] [0]=X) && (board [2] [1]=X) && (board [2] [2]=X) {
printf("Noughts win\n");
}
return 0;
}
