Several If statements in one single program in C++ ....( different if statements in one single program )

our teacher asked us to create one program in C++ that contain several if-statements ( all kinds of if-statenets ) WITHOUT USING FUNCTIONS!

Im relatively new in C++, although in 100% capable of all kinds of if-statements, i have no idea how to but them in one single program!

I don't know what to do! out teacher give us a small hint ( since we are so desperate ): ). He told us that we should use classes ( putting every if-statement in one class ).
