蛇阵函数C语言,蛇形方阵的c语言
c语言怎样设计游戏？
1. 输出1＋1 ＝ ？ 输入2，则输出正确，输入其他则显示错误

2. 24点游戏，输出4个数，输入一行表达式，程序内部计算表达式的值（比较费劲），若＝24则返回胜利，否则失败
3. 五子棋（无AI，否则难），黑白方轮流输入坐标，每次输入完坐标都重新输出一次棋盘上所有棋子，具体方式就是把存储棋子的矩阵挨个输出，无棋输出空格，黑输出＊，白输出o，循环直到判断游戏是否结束的函数返回值为真，即有5子相连才结束。
4. 贪食蛇。这个需要查阅有关＊＊的资料：线程（或计时器），响应键盘按键，随机数等等。蛇每隔单位时间向当前方向前进一步，然后刷新（也就是把画面重新输出一遍），在随机位置产生食物，蛇的尾巴经过食物（即已经消化）后加长一段。按方向键时改变记录当前方向变量的值。加入判断死亡的机制。
这个用控制台（就是和DOS似的，只有press any key to continue之类文字的界面）也可以实现，但是相关资料较少很难找，选择图形编程（windows下常用的软件都是这样，有窗口的）资料更多一些，如果你是在windows上编，就查C语言windows api，刚开始编时不会很方便。由易到难地尝试吧，不必急于用图形编程，控制台也是可以编出好游戏的，这是基础。
c语言 只用循环/选择 输出n阶蛇行/螺旋方阵

不是我做的,不过你可以也看一下!!!!!!!
c语言编贪吃蛇，用什么编译环境，怎么显示贪吃蛇和水果，怎么键盘响应？我菜鸟都不算，求指教。

C语言：编写程序，求一个n×n矩阵对角线元素之和。
求一个n×n矩阵对角线元素之和的源代码如下
public class lianxi28 {
public static void main(String[] args) {
System.out.println("请输入九个整数：");
Scanner in = new Scanner(System.in);
int[][] a = new int[3][3];
for(int i=0;i3;i++){
for(int j=0;j3;j++){
a[i][j]=in.nextInt();
}
}
System.out.println("你输入的n×n矩阵是：");
for(int i=0;i3;i++){
for(int j=0;j3;j++){
System.out.print(a[i][j]+" ");
}
System.out.println();
}
System.out.println();
int sum=0;
for(int i=0;i3;i++){
for(int j=0;j3;j++){
if(i==j){
sum=sum+a[i][j];
}
System.out.println(sum);
}
扩展资料
1、用arrange生成一个数组，元素为0,1,...,8，然后利用reshape生成一个n×n的矩阵。
2、利用for循环将该矩阵的主对角线上的元素相加，然后输出结果。
