编写一个本地c++程序,允许无限输入值

编写一个本地c++程序,允许无限输入值，并将它们储存在空闲存储器中分配的数组中。然后，该程序应该5个一行输出这些值，之后输出输入值的平均值。最初的数组应该包含5个元素。程序应该在必需时创建比旧数组中的值复制到新数组中。

2）用指针怎么做

//#include "stdafx.h"//vc++6.0加上这一行.
#include
using namespace std;
void main(void){
int *p,*pt,*px,ln,i,j,k,sum;
cout << "Please input data(Any letter end)...\n";
if((p=new int[5])==NULL){
cout << "Application memory failure...\n";
exit(0);
}
i=0;
ln=5;
while(cin >> p[i]){
if(++i==ln){
if((pt=new int[ln+5])==NULL){
cout << "Continue to apply for memory failure...\n";
exit(0);
}
memcpy(pt,p,sizeof(int)*ln);
px=p;
p=pt;
delete [ln]px;
ln+=5;
}
}
for(sum=k=j=0;j cout << p[j] << (++k%5 ? ' ' : '\n');
cout << "Their average is " << sum/(i+0.0) << endl;
delete [ln]p;
}

class array{ public: array(){ parr = new int[5]; size = 5; top = 0; sum = 0; avg = 0; } array(const array& a){ size = a.size; top = a.top; parr = new int[size]; for(int i=0; i
