c语言程序设计---屏保程序

在Win_TC里运行 #include<stdio.h>

#include<stdlib.h>

#include<graphics.h>

char a[100]="zhangyafei"

char b[100]

char str[100]=""

int p=1

int i

void main()

{

int gdriver=DETECT, gmode

initgraph(&gdriver, &gmode, " ")

randomize()

do

{

while(!kbhit())

{

i++

if(i==300)

{

i=0

cleardevice()

}setcolor(rand()%16)

circle(rand()%600,rand()%450,rand()%50)

setcolor(rand()%16)

moveto(rand()%getmaxx(),rand()%getmaxy())

lineto(rand()%getmaxx(),rand()%getmaxy())

/*

setbkcolor(rand()%16)

sleep(1)

*/setcolor(rand()%16)

arc(rand()%getmaxx(),rand()%getmaxy(),rand()%getmaxx(),rand()%360,rand()%360) }

cleardevice()

setcolor(6)

settextstyle(0,0,3)

outtextxy(80,getmaxy()/2,"Please Input Password!")

scanf("%s",&b)

cleardevice()

if(strcmp(a,b))

{

p=1

outtextxy(100,getmaxy()/2,"Password is Wrong!")

sleep(1)

}

else

{

p=0

outtextxy(100,getmaxy()/2,"Password is Correct")

sleep(1)

}

}

while(p)

closegraph()

return 0

}

较简单的是用MFC编一个屏缓瞎幕上画图程散哪丛序，测定屏幕大小，图框内缘尺寸要大于屏幕大小，这样显示出来就是full screen. 生成的可执行程序扩冲樱展名用 .scr

把它装入系统，选屏保程序时选它 就可以了。
