Your compiler isn’t smart enough to take into account that the only two options for side are left and right, so it thinks it’s possible for neither return statement to be executed. When side is neither left nor right, your function doesn’t say which value to return.
Do you somewhere have a class or interface named T, or are you using T as a concrete type name somewhere instead of as a type parameter (which means you might have forgotten somewhere else, for example in an enclosing class, to specify that T is a type parameter)? I can reproduce your problem with … Read more
You really should fix whatever’s causing the warning, but you can control visibility of errors with error_reporting(). To skip warning messages, you could use something like:
one has not been assigned so points to an unpredictable location. You should either place it on the stack: or dynamically allocate memory for it: Note the use of free in this case. In general, you’ll need exactly one call to free for each call made to malloc
-Wall doesn’t include many options. -Wconversion is one of them and warns about the behavior you’re interested in. See http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
If you call the function with a first argument of 0 the loop is never executed and the return statement is, thus, never reached. Falling of the end of a non-void function is undefined behavior. My personal guess is that the return statement was meant to one level up, i.e., in the out block: this would guarantee that the function always returns … Read more
I really can’t see any good reason not to just suppress the warning. The safest way would be to use the warnings.catch_warnings context manager to suppress the warning only where you anticipate it occurring – that way you won’t miss any additional RuntimeWarnings that might be unexpectedly raised in some other part of your code: … Read more
This warning means that two projects reference the same assembly (e.g. System.Windows.Forms) but the two projects require different versions. You have a few options: Recompile all projects to use the same versions (e.g. move all to .Net 3.5). This is the preferred option because all code is running with the versions of dependencies they were … Read more
I’m new to Python and this is my first ever thing I’ve scripted and I’m just wondering what I can do to remove this warning: I’ve tried Googling the answer and nothing that was clear to me came up as far as fixing this. I’m trying to write a program that will compare a continuously … Read more
Instead of doing do It will inflate it with the given parent, but won’t attach it to the parent.
