求几个比较有趣，简单的C语言源代码 小白自己敲着练一下手感

最简单的模拟计时器：

#includestdio.h

#includeconio.h

#includewindows.h

int m=0,s=0,ms=0;  //m是分 s是秒 ms是毫秒

//以下是5个自编函数

void csh( );  //初始化界面

void yinc(int x,int y);  //隐藏光标的函数(y值设为0就会隐藏)

void jishi( );  //计时器运行(每100毫秒变化一次)

void Color (short x, short y);  //设定颜色的函数(y设为0就是黑底)

void gtxy (int x, int y);  //控制光标位置的函数

int main(  )  //主函数

{  csh( );

   getch( );

   while(1)

       { jishi( );

         Sleep(100);  //间隔100毫秒

         if( kbhit( ) )break;  //有键按下就退出循环

       }

    return 0;

}

void csh( )   //初始化界面

{Color(14,0);    //设定淡黄字配黑底

printf(“\n\n\t    计时器”);

Color(10,0);   //设定淡绿字配黑底

printf("\n\t┌───────────┐");

printf("\n\t│           │");

printf("\n\t└───────────┘");

gtxy(10,4);   //光标到屏幕第10列4行处输出

Color(7,0);   //恢复白字黑底

printf(" 00:00:00 ");

yinc(1,0 );   //隐藏光标(yinc代表隐藏)

return;

}

void jishi( )  //计时器运行

{ms+=1;

if(ms==10){s+=1;ms=0;}

if(s==60){m+=1;s=0;}

gtxy(10,4);

Color(9,0);   //设定淡蓝字配黑底

if(m9) printf(" %d:",m);

else printf(" 0%d:",m);

Color(14,0);   //设定淡黄字配黑底

if(s9) printf("%d:",s);

else printf("0%d:",s);

Color(12,0);   //设定淡红字配黑底

printf("0%d",ms);

}

void gtxy (int x, int y)   //控制光标位置的函数

{ COORD pos;

pos.X = x;

pos.Y = y;

SetConsoleCursorPosition ( GetStdHandle (STD_OUTPUT_HANDLE), pos );

}

void Color (short ForeColor= 7, short BackGroundColor= 0)   //设定颜色的函数

{ HANDLE  handle = GetStdHandle ( STD_OUTPUT_HANDLE );

SetConsoleTextAttribute ( handle, ForeColor + BackGroundColor * 0x10 );

}

void yinc(int x,int y)   //隐藏光标的设置(gb代表光标)

{ CONSOLE_CURSOR_INFO  gb={x,y};   //x为1-100，y为0就隐藏光标

SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), gb);

}

求C语言源代码，指针与数组编程

1

#includestdio.h

void main()

{

int i,a[10],*p,x,n,flag=0;

p=a;

printf("请输入数组元素的个数n,n=10\n");

scanf("%d",n);

for(i=0;in;i++)

{

printf("请输入第%d个元素\n",i+1);

scanf("%d",p+i);

}

printf("请输入要查找的数字\n");

scanf("%d",x);

for(i=0;in;i++)

if(*(p+i)==x)

{

printf("查找成功,下标为%d\n",i);

flag=1;

}

if(flag==0)

printf("Not found!\n");

}

/*你要的功能在fun函数中实现,注意参数调用的方式*/

#includestdio.h

#define N 3/*可以改*/

#define M 3/*可以改*/

void fun(double a[][M],int n,int m);

void main()

{

double a[N][M]={1,60,35,90,90,95,68,95,83};

fun(a,N,M);

}

void fun(double a[][M],int n,int m)

{

int i,k;

double *p=a[0][0];

for(i=0;in*m;i++)

if(*(p+i)60)

{

printf("%d:",i/n);

for(k=0;kM;k++)

printf("%-7.2f",*(p+i/n+k));

printf("\n");

i=i/n+k-1;

}

}

我的C语言项目是餐饮管理系统，求个源代码
