no, every function can not return a value. for example
void name()
{
cout<<"Hello world";
}
this function does not return any value due to the key word void that tells the compiler that the function does not returns a value.

What is return value 1?
Return value 1 from a function is a true value and generally means success. Return value 1 from the outermost function, i.e. to the shell, however, is a failure indication, and the value is dependent on the design of the code. In other words: context-dependent, always consult the documentation.

What is a return statement used for?
It means end the function. Functions automatically end when execution reaches the end of the function, but you can return from a function at any point within the function with a return statement. If the function returns a value to its caller, you must provide a reachable return statement along with the value you wish to return.

When a function does not return a value what kind of function is it called?
In most computer languages, a procedure that returns a value is called a function and a procedure that does not return a value is called a subroutine or subprogram. Usually the languages treat the passing of arguments/parameters differently between functions and subroutines. The C language does not distinguish between them. A subroutine that does not return a value is define as a "void" function indicating that no return value is used or available.
What does a void method do?
