How to 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 is the error 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 a void function Python?
In Python, it is possible to compose a function without a return statement. Functions like this are called void, and they return None, Python’s special object for “nothing”. Here’s an example of a void function: Calling the two functions, you first notice the slight difference in the output.
What does control reaches end of non void function mean?
If we run this c++ code it works fine and terminates but we get an error at the 8th line saying control reaches end of non-void function. To understand this error we first have to understand the working of the compiler a bit in detail. There are two important kinds of error which occurs while running a program.
Why is there no return statement after for loop?
You are getting this error because if your for loop breaks due to breaking condition i < n; then it don’t find any return statement after for loop (see the below, I mentioned in code as comment). If for loop break due to i >= n then control comes to the position where I commented and there is no return statement present.
Why do we get an error when the function fun is false?
The compiler is just checking the syntax and it interprets that for the function fun if the if condition is false, the flow of the program will reach line 8 and it won’t be returning any value and therefore we get the error.
When do infinite loops fall under run time error?
Run-time error: Error which occurs when the program syntax is correct but there is some problem while the program is run. Generally invalid memory access, infinite loops fall under runtime error.
