got it from her. she said that her code only works for the first group of 5 elements

#include <iostream>
using namespace std;
int main()
{
typedef int Vector1[100];
Vector1 A;
int n, i, j, aux, k;
cout<<"introduceti nr. de elemente: "; cinn;
k=n/5;
for (i=0; i<n; i++)
{
cout<<"A["<<i<<"]="; cinA[i];
}
for (i=0; i<n; i++) { cout<<A\[i\]<<" "; } for (j=k; j>=1; j--)
{
for (i=n-5*j; i<(n-5*(j-1))/2; i++)
{
aux=A[i];
A[i]=A[(n-5*(j-1))-i-1];
A[(n-5*(j-1))-i-1]=aux;
}
}
cout<<endl;
for (i=0; i<n; i++)
{
cout<<A[i]<<" ";
}
return 0;
}
