我要來試圖從矩陣比較字符比較字符,但它不會增加任何價值,我不知道爲什麼試圖從矩陣C
所以這裏是我的代碼:
#include <stdio.h>
#include <math.h>
#include <assert.h>
#include <limits.h>
#include <string.h>
#include <stdlib.h>
#define MAX_LINES 1000
#define MAX_LINE_LENGTH 1000

}
char **ints2_new(int rows, int cols)
{
char **result = (char **) malloc(rows * sizeof(char *));
char *p = ints_new(rows * cols);
for (int i = 0; i < rows; i++, p += cols)
result[i] = p;
return result;
}
int str_readline(FILE *f, char *s)
{
int result = EOF;
char *p = fgets(s, INT_MAX, f);
if (p != NULL)
{
result = (int) strlen(s);
if (result > 0 && s[result-1] == '\n')
s[--result] = '\0';
}
return result;
}
char *str_dup(const char *s)
{
char *result = (char *) malloc(strlen(s) + 1);
strcpy(result, s);
return result;
}
int strings_read(FILE *f, char **a)
{
int result = 0;
char line[MAX_LINE_LENGTH + 2];
while (str_readline(f, line) != EOF)
a[result++] = str_dup(line);
return result;
}

}
}

return result;
}
void points(char **m, int rows, int cols)

int player1 = 0; //O's

我程序員必須閱讀一堆'X','O'和'。'。
如果有3「X」中的行(垂直,水平或對角線)播放器2得到1點上,如果發生同樣的情況爲「0」時,播放器1得到1分。 ''不要指望任何點數。
我的矩陣必須有最少3個行列數和最大1000行和cols。
例如: 如果我把控制檯
XXO
OXO
OXO
玩家1和2各得1分
,如果我把:
XXXXXO //(int this line Player 2 get 3 points because there are 3 times 3 X in a row)
OXOXOO
OXOOXO
OXOXOO
玩家1得到5分 和球員2得到6分
所以我problema爲w ith功能「count_points」它不計算任何點,當我打印「結果」它總是給我0分。
我不能比較2個字符,如果他們在一個矩陣屬於?
感謝
我覺得啞巴,這不是第一次這個錯誤發生在我身上。謝謝 –
