What is the diffrence between type conversion and type casting?
It would be great if you explain with an example :P

Basically conversion is automatic and lossless. For example you define something like this:
float a = 5;
then compiler converts 5 to 5.0 so int to float.
Casting is something what coders do on themselves. For example you have function which returns 5 and then you want to divide it by 2. If you type a = 5/2 you will get 2 as a result. So you have to cast 5 to 5.0 (int to float) manually by:
a = (float)5/2
after that you will receive desired 2.5
Of course it's just a fraction of this subject but it should be enough for now. Read manual for deeper understanding. :)
