Return Statement: Accurate Description in Programming

The C language return statement ends function execution and optionally returns a value to the caller.

In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address. The return address is saved by the calling routine, today usually on the ...

Various mechanisms are used for the case where a subroutine does not return any value, e.g., a return type of ... A method returns to the code that invoked it when it completes all the statements in the method, reaches a return statement, or throws an exception, whichever occurs first.

C return statement is used to end the execution of a function and return a value. It also passes the control back to the function from which it was called. The return statement may or may not return a value depending on the function's return type.

Even functions that don’t explicitly return anything use a return statement behind the scenes — they simply return a default value like None (Python), undefined (JavaScript), or Void (Swift). Every programming language uses a return statement to exit a function and optionally send back a value.

The return statement can only be used within function bodies. When a return statement is used in a function body, the execution of the function is stopped.

It involves specifying "return" followed by the desired value or expression to be sent back. For instance, to return the number 10, the syntax would be "return 10". Subsequently, Python transmits this value to the point in the code where the function was invoked.

"Single Exit" meant that a function should only return to one place: the statement immediately following the call. It did not mean that a function should only return from one place.

Huge block of if-else statements, each with a return? That is nothing. Such a thing is usually easily refactored. (atleast the more common single exit variation with a result variable is, so I doubt the multi exit variation would be any more difficult.) If you want a real headache, look at a combination of if-else and while loops (controlled by local booleans), where result variables are set, leading to a final exit point at the end of the method.
