I am kind of stuck dude's , i recently started my first c++ course and i could tell you this much my teacher is next to nothing , and therefore i need some sort of help ,

i need to example to the exam person what the following mean

#define
int main()
return ( i think this means it returns a value )
void main() ( this one means no value is being pass throught)
cout<< ( this mean a string is being out putted )
cin>> ( receive a input from a keyboard )
; semi colon ( this tell the preprocessor which line to compliler )
// ( this is comment )


so you see if there was a online reference book free i can just check the meaning of the above and hopefull pass with some hands one practise .


my second question is i want to include in some of my basic program some basic graphic is this possible in C++ if so how
