Hi, I understand that the two are the same. But I would like to know why is there the tendency to put an 'underscore' at the end of the variables, like nodeID_ , msg_ , packetSize_, etc . I understand that in naming a variable there is no extra meaning. But is there any naming convention or any benefit of it for differentiating with something else. ns2 is filled with all these type of variable names.
