无聊程序---数字冰雹
我刚学c,编了这个来练练手,呵呵,很简单的[s:258]
#include "stdafx.h"
#include<iostream>
using namespace std;
int a;
int b;
int n;
int _tmain(int argc, _TCHAR* argv[])
{
n=1;
cout<<"请输入检测数字:";
cin>>a;
cout<<"\n";
while(a!=1){
if(a%2==0)
a=a*0.5;
else
a=(a*3+1)/2;
cout<<"第"<<n<<"个数:"<<a<<"\t";
n++;
};
cin>>b;
return 0;
}
不过,谁能告诉我怎么让它执行完后返回重新执行吗???
还有,"cin>>b;"这条是多余的,但不加的话计算完毕就关掉了,看不到结果.
