Lecture 13: Pointer Parameters
Activity: Drama
We have just seen the syntax and purpose for using pointer parameters.
Today we will learn more about a function you saw in today's lecture.
As a class, we will act out a mini-drama that demonstrates the execution
of the following code.
/* interchange *p and *q */
void swap (int *p, int *q) {
int temp;
temp = *p;
*p = *q;
*q = temp;
}
/* somewhere in another function */
...
int a, b;
a = 4;
b = 7;
swap(&a, &b);
