Question

13) Assume that the following program is implemented using the shallow-access method using a stack for each variable name. Show the stacks for the time of the execution of fun3, assuming the calling sequence is:

Answer 1

void fun1() {

floata;

...

}

void fun2() {

intb, c;

...}

void fun3() {

floatd;

... <---------------- 1

}

void main() {

chare, f, g;

...

}

The calling sequence for this program execution to reach fund is:

main calls fun2

fun2 calls fun1

fun1 calls fun1

fun1 calls fun3
