1. What is the output of the following code? (Note that there are no endl's, all output is on a single line) void fun(int &a, int b, int &c); int main() { int a = 1; int b = 2; int c = 3; fun(a, b, c); cout << a << '-' << b << '-' << c << '-'; fun(b, c, a); cout << a << '-' << b << '-' << c; return 0; } void fun(int &a, int b, int &c) { a = a + 3; b = a * 4; c++; }

2.. If test() were called 3 more times, what would be last line printed by test()?

3. What is the output of the following code? (Note that there are no endl's, all output is on a single line) int vol(int s); int vol(int x, int y, int z=1); int main() { cout << vol(2) << "-"; cout << vol(3, 2) << "-"; cout << vol(3, 2, 4); return 0; } int vol(int s) { return s * s * s; } int vol(int x, int y, int z) { return x * y * z; }
