No matter how complicated it is, any set of steps can always be reduced to combinations of the two basic structures of sequence and loop.

Given the function, and the main function calling it: What is the output of the following code if you omit the ampersand (&) from the first parameter, but not from the second parameter? (You are to assume this code is embedded in a correct function that calls it.):

``` #include using namespace std; void func(int & x, int & y) { int t = x; x = y; y = t;} int main() {int u = 3; v = 4; // ... cout endl;func ( u, v )cout // ... ``` a) 3 4 3 3 b) 3 4 4 3 c) 3 4 3 4 d) 3 4 4 4

Compare the my traceroute(mtr) command to the traceroute command.

What will be an ideal response?
