My C++ book says that if I have int anArray; and I try to evaluate anArray = 0; the program will simply overwrite whatever value is stored in the next memory address past the end of the ...
If there's a bug that triggers undefined behavior in a piece of code, is the undefined behavior consistent each time running it? and changes each time compiling it? For example if you had some C code ...
Some hyper-modern C compilers will infer that if a program will invoke Undefined Behavior when given certain inputs, such inputs will never be received. Consequently, any code which would be ...
I hope this question fits this site. You may know you can't detect undefined behaviour in C using compilers - and some tools (static analysis) can help you detect it. My question is more empirical - I ...
In a C implementation where int can hold all values of type unsigned short, standard integer promotion rules dictate that given the code: unsigned short x=(USHORT_MAX+1)-3; // Or just -3 x*=x; a ...
I was reading this question on SO which discusses some common undefined behavior in C++, and I wondered: does Java also have undefined behaviour? If that is the case, then what are some common causes ...
Recently I came across a number of undefined features in C, one of them being the following: http://stackoverflow.com/questions/8698048/behaviour-of-non-const-int-pointer-on-a-const-int Could ...
C\C++ specifications leave out a large number of behaviors open for compilers to implement in their own way. There are a number of questions that always keep getting asked here about the same and we ...
Just a random observation, it seems that on StackOverflow.com, there are questions about if "++i == i++". That question gets asked all the time though, I think I saw it asked about 6 or 7 times in the ...
