(c++) STL Priority Queue with a class, trouble overloading the comparator

2021.10.20 22:55 ThisGuyEveryTime (c++) STL Priority Queue with a class, trouble overloading the comparator

Hello,
My assignment is to create program that monitors arrivals events to bank line. The program will read from a file containing int pairs (arrivalTime, transcationTime). It will create a instance of customer class for each pair and then add those pairs to an Priority Queue of class event. I am currently trying to understand what I am doing wrong in overloading. I know that I need to overload the comparator that is standard with the Priority Queue STL. Each way that I have tried to overload the function I get the error:

Severity Code Description Project File Line Suppression State Error C2678 binary '<': no operator found which takes a left-hand operand of type 'const _Ty' (or there is no acceptable conversion) Assignment 9_2 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\include\xstddef 127 
I understand there is issue with the way that I plan to do the rest of the assignment but I can even get my code to compile because when I push anything to the priority queue it will need to do a comparison first. Below is my code, thank you in advance for any help you can provide.
#include  #include  #include  using namespace std; class customer { public: int arrivalTime; int transcationTime; customer(int arrivalTime, int transcationTime); }; customer::customer(int arrivalTime, int transcationTime) : arrivalTime(arrivalTime), transcationTime(transcationTime) {}; class event { public: customer customerEvent; event(customer& paramCustomer); bool operator<(const customer& paramCustomer); }; event::event(customer& paramCustomer) : customerEvent(paramCustomer) {}; bool event::operator<(const customer& paramCustomer) { if (customerEvent.arrivalTime < paramCustomer.arrivalTime) { return true; } else { return false; } } int main() { customer first(1, 3); event fistEvent(first); cout << fistEvent.customerEvent.arrivalTime << endl; priority_queue testQueue; testQueue.push(fistEvent); }

2021.10.20 22:55 roadkill0000 Soviet - T1/T2 viability? Shock vs Penals?

Hey all. UKF Main player here, want to go back to Soviet again but its been a very very long time.
Had some basic questions:
-How viable are shock troops? how many to have?
-T1 vs T2: which is better? I notice a lot of T1 builds.. people making tons of penals.. should I go both T1 and T2?
- would you combine shock troops with penals? or just go T2?
-conscripts.. how many do you normally make?
-any good basic build order you could recommend for me? ( I like the look of Shock Mortar Heavy and Urban Assault )

Thanks!
