Pass by Value in Java

Variable Declaration and Memory

When you declare a variable of any type (including class/reference types), some space is reserved in memory in order to hold the value of the variable. The variable is just a symbolic name for this value in memory.

Let's say we declare a long.

long x;

Git Examples

Configuration

The first thing you'll want to do is configure git on your nike account.

$ git config --global user.name "Your Name Here"
$ git config --global user.email "your_email@youremail.com"
$ git config --global --add color.ui true

mepcotterell

Assume the following:

include "range.h"

using namespace mepcotterell;

Then you can do cool stuff like this:
