how to use array Allow the user to specify the number of inputs to be used (up to a maximum number)??
is it something like this??

const int SIZE = 30;
int a[SIZE];
int i,n,h;

cout<<"Enter the number of Reistor except Rf:";
cin>>n;

for(i=0;i<n;i++)
{
cout<<"Enter the resistance of R"<<a[i];
cin>>h;
}
return 0;
}

#include <vector> and use a std::vector<int>.

If you have a known maximum number, then there's no need to get vectors involved. Simply store that maximum in a variable somewhere. The fact that the array is bigger than that doesn't matter---you simply ignore any slots in it beyond that value.
