在定义函数时有时在语句前,有的在语句后。

这是我刚编完的C++程序,用于双色球的抽奖

<br>源代码如下:

<br>#include<iostream.h>

<br>#include<stdlib.h>

<br>#include<time.h>

<br>#include<windows.h>

<br>//#include<system.h>

<br>

<br>void NUM()

<br>

<br>int main()

<br>{

<br>int i,j,n

<br>char a

<br>cout<<".....开始?<Y/N>:"

<br>cin>>a

<br>if(a!='Y'&&a!='Y'+32)return 0

<br>for(j=0j++)

<br>{

<br>cout<<"输入投注的注数:"

<br>cin>>n

<br>

<br>for(i=0i<ni++)

<br>{

<br>

<br> cout<<"第"<<i+1<<"注为:"<<endl

<br> srand((unsigned int)time(0))

<br> Sleep(4000)

<br> NUM()

<br> cout<<endl

<br>}

<br>cout<<".....继续吗?<Y/N>:"

<br>cin>>a

<br>if(a=='Y'||a=='Y'+32)continue

<br>else

<br>{

<br> cout<<".......投注结束......"<<endl

<br> break

<br>}

<br>}

<br>return 0

<br>}

<br>

<br>void NUM()

<br>{

<br>int i,j,t

<br>int ball[6]={0}

<br>srand((unsigned int)time(NULL))

<br>cout<<"红球号码为:"

<br>for(i=0i<6i++)

<br>{

<br> t=rand()%33

<br> for(j=0j<6j++)

<br> {

<br> if(t==ball[j]||t==0)

<br> {

<br> t=0

<br> break

<br> }

<br> }

<br> if(t==0)

<br> {

<br> i--

<br> continue

<br> }

<br> ball[i]=t

<br>}

<br>for(i=0i<5i++)

<br>{

<br> for(j=0j<5-ij++)

<br> {

<br> if(ball[j]>ball[j+1])

<br> {

<br> t=ball[j+1]

<br> ball[j+1]=ball[j]

<br> ball[j]=t

<br> }

<br> }

<br>}

<br>for(i=0i<6i++)cout<<ball[i]<<" "

<br>cout<<endl

<br>cout<<"蓝球号码为:"

<br>cout<<rand()%15+1<<endl

<br>

<br>}

<br>

<br>用户手册:

<br>程序运行后,输入你所需要的注数

<br>程序每隔5秒产生一注号码

<br>

<br>示例:

<br>.....开始?<Y/N>:Y

<br>输入投注的注数:5

<br>第1注为:

<br>红球号码为:11 18 19 22 26 31

<br>蓝球号码为:13

<br>

<br>第2注为:

<br>红球号码为:3 6 7 27 28 32

<br>蓝球号码为:9

<br>

<br>第3注为:

<br>红球号码为:3 5 17 19 24 32

<br>蓝球号码为:9

<br>

<br>第4注为:

<br>红球号码为:2 11 19 25 29 32

<br>蓝球号码为:3

<br>

<br>第5注为:

<br>红球号码为:1 12 14 23 28 31

<br>蓝球号码为:1

<br>

<br>.....继续吗?<Y/N>:N

<br>.......投注结束......

<br>Press any key to continue
