Question

I’m trying to get a reference to const QString &a outside of my function i.e.

void function(const QString &a)
{
    //code
}

void otherFunction()
{
    // code <<<<< 
    // I'm unsure how I would be able to get a reference to 
    // const QString &a here and use it. 
}

How could I get a reference to a in otherFunction?

For example you can define QString a as a class member 🙂
So you can access this variable from any method of your class:

classMyCoolClass
{
public:
  void function();
  void otherFunction();    
private:
   QString a;
};
