Chapter 5, Problem 11PS
Consider the following skeletal C program:
void fun1(void); /* prototype */
void fun2(void); /* prototype */
void fun3(void); /* prototype */
void main() {
int a, b, c;
. . .
}
void fun1(void) {
int b, c, d;
. . .
}
void fun2(void) {
int c, d, e;
. . .
}
void fun3(void) {
int d, e, f;
. . .
}
Given the following calling sequences and assuming that dynamic scoping is used, what variables are visible during execution of the last function called? Include with each visible variable the name of the function in which it was defined.
- a. main calls fun1; fun1 calls fun2; fun2 calls fun3.
- b. main calls fun1; fun1 calls fun3.
- c. main calls fun 2; fun2 calls fun3; fun3 calls fun1.
- d. main calls fun 3; fun 3 calls fun l.
- e. main, calls fun 1; fun 1 calls fun 3; fun 3 calls fun 2.
- f. main calls fun 3; fun 3 calls fun 2; Calls fun 1.
