What is implicit conversion?

Short answer. Conversion done automatically.

How do you write an explicit cast?

(double) x.

Remember

Implicit: done automatically
Explicit cast: (double) x

Seven divided by two gives three. Where did the half go? Int divided by int drops the decimal. A cast turns seven into a double first. Now it prints three point five. Implicit conversion is automatic. A cast is written by you.
