how to access the different nodes of my simulation in OMNet++?

Question

I want to get nodes of the network simulation and I found this piece of code:

int nodeID = getId();
cModule* parent = getParentModule();
cModule* module;
this->num_nodes = parent->par("numHosts");
for(int i = 1; i <= simulation.getLastModuleId(); i++)
    {
        module = simulation.getModule(i);
        if (module->getId() != nodeID)
        {
             // Some code
        }
    }

But when I try to compile it I have the error:

use of an undeclared identifier for "simulation".

Add the following line at the beginning of your code:

auto simulation = getSimulation(); 

and for simulation change dot operators into arrows, ie:

simulation->getLastModuleId() 
simulation->getModule(i)
