What is the difference between explicit and implicit type casts?

Question

Can you please explain the difference between explicit and implicit type casts?

Answer 1

Explicit cast:

int x = 0;
float y = 3.8f;

x += (int) y; //Explicit cast.

This tells the compiler that the cast was intentional and that you know that the fractional part will go lost. The compiler won't complain.

Implicit cast:

int x = 0;
float y = 3.8f;

x += y; //Implicit cast

The compiler will complain because the fractional part will be lost when converting float to int.
