In the code below the output is 2. This code is used in a challenge and I get an error when I select the answer 2. It accepts as correct the answer 1 which I believe is wrong. If you agree please thumbs up. If you find any other errors please post them here! #include <iostream> using namespace std; int main() { for(int i=1; i>=1; i++) { if(i<1 || i>1){ cout << i; break; } } return 0; }

Where all can you "pull" (source) an image from; meaning, does it have to be a URL, or can it be a file (is that what is meant by "relative" and "absolute")? Also, how do you "format" the image/where do you put it so it can be accessed by the code and used on the webpage?

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

Isn't this just a reoccurring function called from within itself until a particular set of conditions are met? I don't know it just seems like shorthand to me. Like a do-while loop. I am sure it could be used for more than just factorials.

So i understand that x++ is changing the vafiable after it is used and ++x before. But in the example of x = 5 y = ++x Why does y not equal 6 when x gets changed before use.

so although using srand(time(0)) can be used to get truly random numbers, how truly random are they? For example, if one were to call this method at the same time (in this example, if one were to use this command at 51s) each time would the numbers generated be the same??? If so, are the numbers still truly random?? And if this theory is true, how can one generate truly random numbers that cannot repeat based on external variables (e.g., time)?
