C++ Reactive Programming

Aggregation based on Stream data

In this section, the Stream item is a user-defined type to represent an employee, and the code is intended to group the input Stream based on the roles and salaries of employees:

#include "rxcpp/rx.hpp" 
 
namespace Rx { 
    using namespace rxcpp; 
    using namespace rxcpp::sources; 
    using namespace rxcpp::subjects; 
    using namespace rxcpp::util; 
} 
 
using namespace std; 
 
struct Employee { 
    string name; 
    string role; 
    int salary; 
}; 

The libraries and namespaces required in the code are included, and the data structure to represent an Employee is declared. The Employee type is a simple structure, with data items such as name, role, and salary. We have treated the salary field as an integer:

int main() { Rx::subject<Employee> ...
