Look at the labels and variable names and make sure you're using the variable name, not the label.
Core Guidelines This specific variable named x can only be referred to within the addtwo function (though of course other functions can also have variables called x).

Overview Floating-point numbers. Well you may assume that the compiler should assign your primitive type variable with meaningful values like 0 for int, 0.0 for float.
Why aren't uninitialized variables always 0 in C? - Quora The following options control the dialect of C that the compiler accepts:-ansi. In common mathematical notation, the digit string can be of any length, and the location of the radix point is indicated by placing an explicit "point" character (dot or comma) there.

When we define a variable, we should give it an initial value unless we are certain that the initial value will be overwritten before the variable is used for any other purpose. Between the last two I decide based on whether the two values must really be the same type (bool previousInputValue, presentInputValue;) or if they just happen to be the same type now but don't really need to be (uint8_t height, width; might turn into uint8_t height; uint16_t width; in the future and should have been uint8_t height; uint8_t width; to begin with).

For now, you should always initialize your variables because the cost of doing so is miniscule compared to the benefit. Once you are more comfortable with the language, there may be certain cases where you omit the initialization for optimization purposes.
