c项目开发源码

A. 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：

#include<stdio.h>

#include<conio.h>

#include<windows.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(“ 计时器”);

Color(10,0); //设定淡绿字配黑底

printf(" ┌───────────┐");

printf(" │ │");

printf(" └───────────┘");

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(m>9) printf(" %d:",m);

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

Color(14,0); //设定淡黄字配黑底

if(s>9) 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);

}

C. 求C程序源代码

用for
语句和getch(
);putchar
(‘*’);来实现的，而getch
不分区另ENTER和BACKSPACE等特殊键，不好控制它的结束。因此只有避过问题强行规定密码必须是8位的，但在输入密码时仍然不允许用户输入ENTER和BACKSPACE等特殊键。
以下程序功能：
接受所有打印字符。
不接受控制字符，如Ctrl+
，Alt，F1等。
可使用退格键删除以输入字符。
回车键为密码输入完毕
可定义最大字符数。当输入字符数等于最大字符个数时，视为密码结束。

E. 求个用c/c++编写windows程序源代码

下面是完整程序，MS VC++ 6.0 编译器。
主要用途，用鼠标点击调节 RGB 数值，椭圆里显示 对应的颜色。
程序里有多余的码，你可以删去。（一个多余是试验鼠标移动时连续显示坐标数值，还有一个多余部分是调用Vfw32.lib播放一个avi视频。）
