C++ Programming Problem #4 : Fibonacci
Fibonacci sequence is simply by adding up the two numbers before it. The numbers are similarly related to Lucas Numbers which is another mathematical sequence.

This is how to manipulate the location of your text in pixels concept. By using the X and Y coordinates, you have to make sure the right coordinates for your output is in perfect shape.
gotoxy(x,y);

This is how to change the text attribute color. A specific number corresponds to a specific color.
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), #);
