写个program 让你输入正数 然后你一直输入 个正数。。 如果输入负数的话提示你输入了负数 等到输入0的时候就出现 你刚才输入几个正数
例子：
enter a positive number (0 to end): 2
enter a positive number (0 to end):3
enter a positive number (0 to end):-2
youhave entered a negative integer.
enter a positive number (0 to end):3
enter a positive number (0 to end):0
------------------------------------
you have input 3 positve integers.

you have input 3 positve integers.
#include <iostream.h>
int main(void)
{
int n, p=0;
do
{
cout<<"enter a positive number (0 to end): ";
cin>>n;
if (n>0) p++;
else if (n<0) cout<<"you have entered a negative integer. "<<endl;
}while(n);
cout<<"------------------------------------"<<endl;
cout<<"you have input "<<p<<" positve integers."<<endl;
return(0);
}
