What is 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.
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.
How do you remove control reaches at the end of a non-void function?
Another way to get rid of the warning is to add assert(false); at the end of the function, to clearly tell the compiler (and human reader) that you deliberately omitted the else case because you are sure it cannot happen.
Why does my compiler keep giving me the error?
My compiler keeps giving me the error: There’s actually three errors in this project. My project is due in September 2015, so please help! Thanks in advance. You have your classes’ function definitions inside your main function, which is not allowed.
Is it OK to include A.C file with a function definition?
Now, including a .c file is Not Recommended in general, but it can work (for beginners). After you get things working, then the “right thing” is to make a separate .h file with the function declarations (prototypes) and include that file in your main file.
Why is a call not allowed in Arduino?
This error can be applied to any method call. We call it ‘call’ because you’re not defining the method, you’re just using it. You don’t need to know how does it work. It is enough knowing that you need to give the two values, and the output you will receive.
