No. For example, take the following grammar: E -> TE’ | T E’ -> +TE’ | -TE’ | T T -> FT’ | F T’ -> *FT’ | /FT’ | F F -> cte | (E) It is the well known grammar for arithmetic expressions, written in LL(1) form. It is also a well known … Read more
The first character in an identifier must be a-z, A-Z, or underscore, for 53 possibilities. Subsequent characters can be digits 0-9 too, for 63 possibilities. So n characters give 53 * (63**(n-1)) legal identifiers: Length Names 1 53 2 3339 3 210357 // much less than 1000000 4 13252491 // much more than 1000000 Some … Read more
Linux uses a “guard area”. It puts one or more access-protect pages at the end of the stack for each thread. If the program accesses the guard area, the OS handles the fault. If the thread is already using its max permitted stack then it terminates something (the thread or the whole process, I don’t … Read more

You can’t make a video file into an executable. You can write a video player in Python which implements the functionality you desire and then use something like py2exe to make it into an executable, but that would involve writing a video player in Python. There is no programming language that will make a video … Read more
The problem was in the class Program Main(){ method = cc.CompileCode(file, “testNamespace”, “Class1”, “webRequest”, true, arguments);} The string classname was not the good one and didn’t pointed to the real document I wanted to compile. The good path was method = cc.CompileCode(file,”testNamespace”, “WebRequest”,”webRequest”, true, arguments);} That’s why the Type type; couldn’t get something instead of … Read more
Check http://en.cppreference.com/w/cpp/language/eval_order especially the part which discusses “Undefined behavior”. Basically it’s not a bug in the compiler. The language says what you’re doing is undefined. solved Compiler issue or some bug in code block of c [duplicate]

Maybe a concrete example would help. Try this: #include <stdio.h> const double step_size = 5.0; // degrees of arc struct Location { double latitude; double longitude; }; void go_north(struct Location *const loc) { loc->latitude += step_size; } int main() { struct Location there; there.latitude = 41.0; there.longitude = -101.5; go_north(&there); printf(“Lat. %6.1f, long. %6.1f.\n”, there.latitude, … Read more
