a) Hand-trace the following program and determine and write down what is the output of the code.

b) Run the code and compare the program output to your hand-traced result obtained from part (a).

#include

#include

using namespace std;

void f();

int x = 5;

int main()

{

cout << "x = " << x << endl;

int x = 6;

cout << "x = " << x << endl;

{

int x = 7;

cout << "x = " << x << endl;

}

cout << "x = " << x << endl;

f();

return 0;

}

void f()

{

cout << "x = " << x << endl;

int x = 8;

cout << "x = " << x << endl;

}
