Call the copy constructor.

Let me explain:

Shoe shoe1; // calls the constructor
Shoe shoe_copy(shoe1); // copy constructor
Shoe shoe_copy = shoe1; // copy constructor, even if it seems it's...

int input;
const int ANSWER = random_integer1 + random_integer2;

do
{
cin >> input; // get input
} while(input != ANSWER);
/* this will repeat as long as input is not equal to the answer....

Is it an image you changed manually from .jpg (for example) to bmp by just renaming the file?
