C coding: Write a function win() with the following prototype: int win(char boar

Question

C coding:

Write a function win() with the following prototype:

int win(char board[6][6], char player)

The function win should return a 1 if the character player is found in three consecutive positions in the board.

Consecutive for this lab means in the same row, or in the same column, NOT on a diagonal.

For the board shown below,

The following values should be returned by win() if called as:

win(board,'A') would return 0

win(board,'B') would return 0

win(board,'D') would return 0

win(board,'G') would return 1

win(board,'O') would return 0

win(board,'X') would return 0

win(board,'Z') would return 1

GIVEN:

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

int win(char a[6][6], char player) {
int i,j;

for(i=0;i<6;i++) {
for(j=0;j<6;j++) {
if(j==4) {
if(a[i][j]==player && a[i][j+1]==player && a[i+1][0]==player) {
return 1;
}
}
if(j==5) {
if(a[i][j]==player && a[i+1][0]==player && a[i+1][1]==player) {
return 1;
}
}
if(a[i][j]==player && a[i][j+1]==player && a[i][j+2]==player) {
return 1;
}
}
}

for(i=0;i<6;i++) {
for(j=0;j<6;j++) {
if(i==4) {
if(a[j][i]==player && a[j][i+1]==player && a[j][0]==player) {
return 1;
}
}
if(i==5) {
if(a[j][i]==player && a[j][0]==player && a[j][1]==player) {
return 1;
}
}
if(a[j][i]==player && a[j+1][i]==player && a[j+2][i]==player) {
return 1;
}
}
}
return -1;
}

int main() {
char board[6][6];
int i,j;
char user;
int gameresult;

printf("Enter 36 values for the 6x6 game board ");
for(i=0;i<6;i++){
for(j=0;j<6;j++) {
scanf("%c ",&(board[i][j]));
}
}

// print the gamr board
for(i=0;i<6;i++) {
for(j=0;j<6;j++) {
printf("%c ",(board[i][j]));
}
printf(" ");
}
do {
fflush(stdin);
printf("Enter the uesr's token to see if they won the game!");
scanf(" %c",&user);
printf(" ");
gameresult = win(board,user);
if (gameresult == 1) {
printf("Player %c won the game!",user);
}
else if (gameresult == -1) {
printf("Player %c didn't win.",user);
}
else {
printf("invalid response from win() ");
printf(" ");
}
while(user!='x');
return 0;
}

Explanation / Answer

// C code
#include <stdio.h>
#include <stdlib.h>

int win(char a[6][6], char player)
{
int size = 6;
int i,j;

for(i=0;i<size;i++)
{
for(j=0;j<size;j++)
{
if(j==4)
{
if(a[i][j]==player && a[i][j+1]==player && a[i+1][0]==player )
return 1;
}
if(j==5)
{
if(a[i][j]==player && a[i+1][0]==player && a[i+1][1]==player )
return 1;
}
if(a[i][j]==player && a[i][j+1]==player && a[i][j+2]==player )
return 1;
}

}
for(i=0;i<size;i++)
{
for(j=0;j<size;j++)
{
if(i==4)
{
if(a[j][i]==player && a[j][i+1]==player && a[j][0]==player )
return 1;
}
if(i==5)
{
if(a[j][i]==player && a[j][0]==player && a[j][1]==player )
return 1;
}
if(a[j][i]==player && a[j+1][i]==player && a[j+2][i]==player )
return 1;
}
}
return 0;
}

int main()
{
char board[6][6] = { {'A', 'B', 'B', 'D', 'E', 'G'},
{'Z', 'A', 'B', 'G', 'G', 'E'},
{'Z', 'B', 'A', 'G', 'G', 'G'},
{'Z', 'Z', 'X', 'G', 'K', 'K'},
{'X', 'X', 'O', 'K', 'O', 'W'},
{'X', 'X', 'O', 'O', 'W', 'W'},
};
int i,j;

for(i=0;i<6;i++)
{
for(j=0;j<6;j++)
{
printf("%c ",(board[i][j]));
}
printf(" ");
}

printf(" ");
  
printf("%d ",win(board,'A'));
// return 0

printf("%d ",win(board,'B'));
// return 0

printf("%d ",win(board,'D'));
// return 0

printf("%d ",win(board,'G'));
// return 1

printf("%d ",win(board,'O'));
// return 0

printf("%d ",win(board,'X'));
// return 0

printf("%d ",win(board,'Z'));
// return 1

  
return 0;
}
