we can compare the main structure of C# with a Human body. We all know that our brain gives us only instruction/command nothing else.But the prossing phase fully complete into our body not in our brain.
For example, we consider a mosquito. If a mosquito sit upon our hand or leg then brain just command that “kill !! Kill upon the mosquito” & our hand goes there & beat upon the mosquito.Brain do not come for beating the mosquito any more.One more thing, where the mosquito sittings brain also gives a proper information to the hand .
So , C# is nothing but like that. Those content that are written into the main class , work like as a instructor or commander. They call many functions from another class or project . These functions have been define before that which function proceed which parts.
