How do you fix control may reach end of non void function?
how can i fix this “control may reach end of non-void function”…
- Create a TokenType “INVALID” and return it.
- Throw an exception.
- Call std::terminate and exit the program.
- Change the return type to bool, return false for bad values of c (and use a “TokenType &” argument as a way to return the output)
What does it mean when control reaches end of non void function?
If control reaches the end of a function and no return is encountered, GCC assumes a return with no return value. However, for this, the function requires a return value.
Can you return nothing in a void function?
Return from void functions in C++ The void functions are called void because they do not return anything. “A void function cannot return anything” this statement is not always true. From a void function, we cannot return any values, but we can return something other than values.
Which function must not use a return statement?
Functions 2: Void (NonValue-Returning) Functions In lieu of a data type, void functions use the keyword “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.
What is the difference between void and non void function?
Answer: The way that a non-void method is called differs from the way that a void method is called in that the call is made from within other Java statements. Since a non-void method always returns a value, this value has to be stored in a variable, printed, or returned to a Java control structure or another method.
What will be the return type of function if the function is not returning anything?
If a function is not returning any values, then we use void as the return type. Void functions do not return a value after the function executes but they are used similarly like value-returning functions.
