  • passing parameters by value, reference, address
void byvalue(int val) {
	val = 10;
}
void byaddr(int *val) {
	*val = 10;
}
void byreference(int &val) {
	val = 10;
}
 
int main(){

	int myval = 5;
	char *foo = new char [10];
	cout << "myval is "<<myval<<endl;
	byvalue(myval);
	cout << "after value myval is "<<myval<<endl;
	myval = 5;
	byaddr(&myval);
	cout << "myval is "<<myval<<endl;
	myval = 5;
	byreference(myval);
	cout << "myval is "<<myval<<endl;
}
  • show labyrinth code and talk about call by reference, then have them act it out on a 5×5 grid on the stage
