Argument Passing

• Strict Evaluation: evalulate the arguments, then call the function

            void fun(int x) { print fun }
            int arg() { print arg; return 2; }
            fun(arg());    // prints arg fun with strict eval
            

• Parameter Passing
• Pass By Value (PBV): copy in the value
• Pass By Reference (PBR): make a brand new reference to the argument

            void foo(int x) { x = x + 2; }
            int w = 4;
            foo(w);
            print w // PBV prints: 4, PBR prints: 6
            

Note: something in C++ is PBR!!
