array question

This program should determine whethet the integer is positive or negative. Then it should copy negative values into aryA and positive value into aryB. lastly, it should display how many values copied into aryA and aryB.

#include <iostream>
using namespace std;

int main()
{
int ary[4], aryA[4], aryB[4];
int count;
int a= 0;
int b= 0;

cout<<"Please enter 4 integer numbers : ";

for (int i=0;i<4;i++)

cin>>ary[4];

cout<<endl;

for (int count=0; count<4; count++)
{
if (ary[4]>=0)
{
b=count aryB[4];

}
else
{

a=count aryA[4];
}
}

cout<< "Array A has "<<a<<"values."<<endl;
cout<< "Array B has "<<b<<"values."<<endl;

return 0;
}
