I have to return to the previous level of the recursion. is the syntax like below right?

void f()
{
   // some code here
   //
   return;
}

Yes, you can return from a void function.

Interestingly, you can also return void from a void function. For example:

void foo()
{
  return void();
}

As expected, this is the same as a plain return;. It may seem esoteric, but the reason is for template consistency:

template<class T>
T default_value()
{
  return T();
}

Here, default_value returns a default-constructed object of type T, and because of the ability to return void, it works even when T = void.

Return from void functions in C++, Yes, you can return from a void function. Interestingly, you can also return void from a void function. For example: void foo() { return void(); }. A void function performs a task, and then control returns back to the caller--but, it does not return a value. You may or may not use the return statement, as there is no return value. Even without the return statement, control will return to the caller automatically at the end of the function.


Sure. You just shouldn't be returning an actual value.

Can I return in void function?, The void functions are called void because they do not return anything. “A void function cannot return anything” this statement is not always true  So a void function can effectively return an integer value by explicitly setting the eax register. You can do this using inline assembly. The compiler will not allow you to use the void function in an expression where an integer is expected.


Yes, that will return from the function to the previous level of recursion. This is going to be very basic explanation, but when you call a function you are creating a new call stack. In a recursive function you are simply adding to that call stack. By returning from a function, whether you return a value or not, you are moving the stack pointer back to the previous function on the stack. It's sort of like a stack of plates. You keep putting plates on it, but than returning moves the top plate.

You could also verify this by using a debugger. Just put a few break points in your code and step through it. You can verify yourself that it works.

Return from void functions in C++, Why do you use "return" at the end of a function that's declared as void? Surely declaring a function as void will would force the compiler to  A void function cannot return anything. The reason you can return a void * is because, as @JohnBode mentions in the comments, "the language standard specifies that a pointer to void may be converted to or from any object pointer type (6.3.2.3/1)". The value of the pointer is pushed on to the stack and then popped off when you return.


Yes, you can use that code to return from the function. (I have to be very verbose here to make Stack Overflow not say that my answer is too short)

Why use "return" at the end of "void" functions? - Talk, A return statement can also return a value to the calling function. If the function was declared with return type void , a return statement  A return in a void method is not bad, is a common practice to invert if statements to reduce nesting. And having less nesting on your methods improves code readability and maintainability. Actually if you have a void method without any return statement, the compiler will always generate a ret instruction at the end of it.


You shouldn't have to have the return there, the program will return to the previous function by itself, go into debug mode and step through and you can see it yourself. On the other hand i don't think having a return there will harm the program at all.

return Statement (C), In a function returning void, the return statement with expression can be used, if the expression type is void. The copy-initialization of the result of  Yes, you can return from a void function. Interestingly, you can also return void from a void function. For example: void foo() { return void(); } As expected, this is the same as a plain return;. It may seem esoteric, but the reason is for template consistency: template<class T> T default_value() { return T(); }


return statement, Void as a Function Return Type. Void functions, also called nonvalue-returning functions, are used just like value-returning functions except void  You can't return NULL in a void function,because NULL is defined by #define NULL 0 in C++,(return 0 or NULL means that you return a value that is int or other type) void function means that it have no return value,you can write code: return; to exit a void function.


Definition of Void in C and C++, So a void function can effectively return an integer value by explicitly setting the eax register. You can do this using inline assembly. The compiler will not allow you  void is surely tricky business, and the reason to allow void as a 'return' from a function call makes sense. There would appear to be no other way to set a temporary to void, I should


In the C programming language, can a void function return any , In some condition we would do short logic and return from function immediately So I think we should allow to return from void function with
