Suggest: 

-Note a[0] should is (z*l+i)%m not l beacause:

"But be careful: the cycle might not begin with the seed!"

#include<bits/stdc++.h>

using namespace std;

int z, i, m, l, test;

int main(){

        ios::sync_with_stdio(0); cin.tie(0);

        while(cin >> z >> i >> m >> l && z && i && m && l){

                vector<int> a(1,(z*l+i)%m);

                do{

                        a.push_back((z*a.back()+i)%m);

                }while(a[0] != a.back());

                cout<<"Case "<<++test<<": "<<a.size()-1<<"\n";

        }

}
