C# if apps

Hello Guys



Sorry for asking a question like this but i don't know where else to ask this. I'm studying computer science at a university my problem is my program development teacher gave us a homework. The homework is write 20 "if" statement apps in c# console but i cannot think of 20 different "if" apps. Can someone please give some ideas of simple "if" apps because I can write the code i just can't think of 20 apps i got like five :

-an app that asks for two number and then tells you which is bigger-an app that asks for a number than it tells you to if it can be divided by 2
-a "guess the number" app
-an app that asks for a number than it decides if its positive or negative
-a font color choosing app

So i need help for writing like 15 more but i can't think of anything else.

Thanks !
