Question

I have a method that is returning a CString and placing it into a variable, however this variable is a parameter in the method. Is there a better way to assign the return of the method into the variable?

Example:

CString foo = "foo";
foo = MakeBar(foo);

Answer 1

Pass foo by reference into the function. In that way it’s understood that it will be an input/output parameter.

void MakeBar(CString &foo)
{
  if(foo == "foo")
    foo = "bar";
}

//...


CString foo = "foo"; 
MakeBar(foo);
