Explicit return statements with expression given are not permitted within a function with a void return type and cause a fatal error. a function may have any number of return statements, whose returned values may have different types. As you may know, there are often different ways to achieve the same thing in programming in general, conditions are no exception here. in this article, we will cover the main difference between. A statement is something that does something. an expression is something that evaluates to some value. some constructs are both statements and expressions.
