Question

what is a statement and expression​

Answer 1

Answer:

A statement is a complete line of code that performs some action, while an expression is any section of the code that evaluates to a value. ... Every expression can be used as a statement (whose effect is to evaluate the expression and ignore the resulting value), but most statements cannot be used as expressions.
