C语言程序设计

从 大一下 开始写博客，记录自己的学习。

而作为一个强迫症（比如我）是不允许做事缺头少尾的。

想了想还是得大一所学的C语言也搬上来，虽然结构老师经常嘲讽

（也不算嘲讽，算是絮叨吧）我的C语言，但是我还是要厚着脸皮继续

学习的。永远保持一颗学徒的心。 加油！

上学期C语言的每次作业或者实验报告我就懒得再写了（太多了），就写一下期末

实训作业吧，有两个题。

1.做一个国际棋盘

例如：

现在看来真是简单，不知道上学期自己做的时候怎么还花了囊么多的时间.....

#define N 8

static char Getboard(int row, int column)//判断棋子的函数
{
    if ((row + column) % 2 == 0) return ' ';
    else if (row<3) return 'b';
    else if (row == 3 || row == 4) return '-';
    else return 'r';
}
static void InitCheckerboard(char board[N][N])//初始化棋盘的函数
{
    int i, j;
    for (i = 0; i<8; i++) {
        for (j = 0; j<8; j++) {
            board[i][j] = Getboard(i, j);
        }
    }
}

static void DislayCheckerboard(char board[N][N])//显示棋盘的函数
{

    for (int i = 0; i<8; i++) {
        for (int n = 0; n<8; n++) {
            printf("%c", board[i][n]);
        }
        printf("
");
    }
}
int main()
{
    char board[N][N];
    InitCheckerboard(board);
    DislayCheckerboard(board);
    return 0;
}

2. 猜单词hangman game

由一个玩家想出一个单词或短语，另一个玩家猜该单词或短语中的每一个字母，

第一个人抽走单词或短语，只留下相应数量的空白与下划线。

这里运行结果图我懒得再去找了（好像保存深度系统里面了），现在用visual studio重新运行的

话，又不知道怎么弄随机库，就这样吧。
