C语言比较有意思的几个小程序

#include < conio.h >

main()
... {
    int i;
    char *s[]=...{"BLACK","BLUE","GREEN","CYAN",
    "RED","MAGENTA","BROWN","LIGHTGRAY",};
    textmode(C80);
    textbackground(0);
    clrscr();
    for(i=1;i<8;i++)
    ...{
        window(10+i*5,5+i,30+i*5,15+i);
        /**//*函数名: window 
        功 能: 定义活动文本模式窗口
        用 法: void window(int left, int top, int right, int bottom); 
        函数中形式参数(int left,  int top)是窗口左上角的坐标,
        (int right, int  bottom)是窗口的右下角坐标, 
        */
        textbackground(i);
        clrscr();
        textcolor(7+i);
        if(i%2 == 0)
        highvideo();
        else lowvideo();
        cputs(s[i]);
    }
    getch();

}

 以上程序显示四个层叠的彩色窗口

 

#include < graphics.h >
#include < time.h >

main()
... {
    int graphdriver = VGA;
    int graphmode = VGAMED;
    int i,height,width
    ;
    unsigned char *temp="Welcome";
    initgraph(&graphdriver,&graphmode,"");/**//*/图形系统初始化函数*/
    settextjustify(LEFT_TEXT,TOP_TEXT); /**//*文本输出位置函数*/
    cleardevice();
    for(i=1;i<5;i++)
    ...{
        setvisualpage(i-1);
        setactivepage(i);
        cleardevice();   /**//*清除图形屏幕*/
        setcolor(12);
        setbkcolor(BLUE);
        settextstyle(TRIPLEX_FONT,HORIZ_DIR,i); /**//*设置用三倍画笔，水平放置，放大I倍*/
        width=textwidth(temp);
        height=textheight(temp);
        outtextxy((639-width)/2,175-height/2,temp);/**//*在指定位置输出字符串*/
        setvisualpage(i);
        setactivepage(i-1);
        cleardevice();
        setcolor(10);
        settextstyle(TRIPLEX_FONT,HORIZ_DIR,i++);
        width=textwidth(temp);
        height=textheight(temp);
        outtextxy((639-width)/2,175-height/2,temp);
        system("pause");
    }
        getch();
        closegraph();
}

这个家伙没啥效果，理论上是应该有字符颜色的不同变化形成动画效果，但是只有字符显示没有动画，..
