Hi guys I came across an exercise which I have no idea about. Here I have to determine the console outputs for the couts and if the function do_something(92) is called :

  string do_something(unsigned int input) {
 unsigned int &i = input; 

 const char* vect = "0123456789ABCDEF"; 
string temp = ""; 

cout << "input=" << input << ", i=" << i << endl;

while (i > 0) { 
short index = input % 0x10; 
temp = *(vect + index) + temp; 
input = input / 0x10; 
cout << "input=" << input << ", index=" << index << endl;
 } 
cout << "input=" << input << ", i=" << i << endl; 
return temp; 
}

Could someone please explain what is going on here ? Thanks!

Why not slap a main() function onto it, compile and run the code and see what you get?

i do know the answers, but I really do not understand them. So it would be really wonderful if someone could explain them to me?

Firstly I agree with what dhayden says... why don't you just compile it

Also you could comment on the lines you don't understand, that would help us to help you...
