C语言怎么写一个简易秒表

用到time.h档案

里面有个clock()函式,返回一个clock_t型别的数字,表示从程式执行开始,CPU的"滴答"数

而在time.h里有个常量CLOCKS_PER_SEC表示每秒钟有多少个"滴答".

这样,(((float)clock())/CLOCKS_PER_SEC)*1000这样的表示式就能得到从程式执行开始到现在的经过的时间.

程式的大致思路是这样的,程式按下1的时候记下当时的程式执行时间.

从这时起,每时刻捡取程式执行时间,然后减去先前的值,就可以得到已经计时的时间了.

只要让使用者按下0结束计时就好了

在conio.h档案里,有个函式kbhit()是个非阻塞函式,用来检查键盘缓冲里有没有按键按下,若有,则返回1,若没有,则返回0,以此来作为判断,若返回1,则捡取按键,测试它是不是0或者1,若返回0,则表示使用者没有动作,继续原来的工作,即继续计时或等待命令.

用c语言写一个简易数独的思路。要程式码

#include<stdio.h>int num[9][9], xy[9][9]int check(int x, int y) {int i, m, n for(i = 0i <9i++)if ((xy[x][y] == xy[i][y]&&i != x)||(xy[x][y] == xy[x][i]&&i != y))return 0 for(i = 0, m = x / 3 * 3, n = y / 3 * 3i <9i++)if (xy[x][y] == xy[m + i / 3][n + i % 3]&&m + i / 3 != x&&n + i % 3 != y)return 0 return 1}void search(int x, int y) {if (x == 9)for(x = 0x <9x++) {for(y = 0y <9y++)printf("%d ", xy[x][y]) printf("\n") }else if (num[x][y])search(x + (y + 1) / 9, (y + 1) % 9) elsefor(xy[x][y] = 1xy[x][y] <= 9xy[x][y]++)if (check(x, y))search(x + (y + 1) / 9, (y + 1) % 9) return}int main() {int i, j for(i = 0i <9i++)for(j = 0j <9j++) {scanf("%d", &num[i][j]) xy[i][j] = num[i][j] }search(0, 0) return 0} 输入为9行9列整数,已知的整数填写对应的数字,尚待计算的未知数字填写0。

该程式码的思路很简单,就是从第一行第一列开始依次填入数字,检查是否是在同一行、同一列、同一宫有没有填入重复数字,如果没有就继续填入下一个数字,如果有就返回。

虽然效率稍低,但原理简单、表述直白、易于理解,更有效率的程式码是使用十字连结串列完成,如有兴趣可继续深入
