Question

3. Consider the following program: 1 int a = 2; 2 void foo(int b) { 3 printf("%d", b); 4 } 5 int main(void) { 6 foo(a); 7 a = 1; 8 } Is it true or false that the value of a passed to foo will always be 2? Explain. Assume that this is the entire program, that this program is stored in persistent memory, and that the program is executed on a bare-iron microcontroller each time a reset button is pushed.

Consider the following program:
1	int a = 2;
2	void foo(int b) {
3		printf("%d", b);
4	}
5	int main(void) {
6		foo(a);
7		a = 1;
8	}
Is it true or false that the value of a passed to foo will always be 2? Explain.
Assume that this is the entire program, that this program is stored in persistent
memory, and that the program is executed on a bare-iron microcontroller each time
a reset button is pushed.

Step 1

The program consists of a global variable `a` initialized to 2, a function `foo` that takes an integer `b` and prints it, and a `main` function. Show more…
