Order of Left and Right Operands To perform the assignment in arr[global_var] = update_three(2), the C implementation must evaluate the operands and, as a side effect, update the stored value of the left operand. C 2018 6.5.16 (which is about assignments) paragraph 3 tells us there is no sequencing in the left and right operands: … Read more
The order is the order they appear in the class definition – this is from section 12.6.2 of the C++ Standard: 5 Initialization shall proceed in the following order: — First, and only for the constructor of the most derived class as described below, virtual base classes shall be initialized in the order they appear … Read more
document.ready() callbacks are called in the order they were registered. If you register your testing callback first, it will be called first. Also if your testing code does not actually need to manipulate the DOM, then you may be able to run it as the code is parsed and not wait until the DOM is … Read more
Operator precedence is defined in the appropriate standard. The standards for C and C++ are the One True Definition of what exactly C and C++ are. So if you look closely, the details are there. In fact, the details are in the grammar of the language. For example, take a look at the grammar production … Read more
Yes, the MSDN article is in error, at least with respect to standard C and C++1. Having said that, let me start with a note about terminology: in the C++ standard, they (mostly–there are a few slip-ups) use “evaluation” to refer to evaluating an operand, and “value computation” to refer to carrying out an operation. … Read more
It depends on the argument type, the called function’s calling convention, the archtecture and the compiler. On an x86, the Pascal calling convention evaluates arguments left to right whereas in the C calling convention (__cdecl) it is right to left. Most programs which run on multiple platforms do take into account the calling conventions to … Read more
No, there’s no such guarantee. It’s unspecified according to the C++ standard. Bjarne Stroustrup also says it explicitly in “The C++ Programming Language” 3rd edition section 6.2.2, with some reasoning: Better code can be generated in the absence of restrictions on expression evaluation order Although technically this refers to an earlier part of the same … Read more
Files on the filesystem are not sorted. You can sort the resulting filenames yourself using the sorted() function: for infile in sorted(glob.glob(‘*.txt’)): print “Current File Being Processed is: ” + infile Note that the os.path.join call in your code is a no-op; with only one argument it doesn’t do anything but return that argument unaltered. … Read more
Construction always starts with the base class. If there are multiple base classes then, construction starts with the left most base. (side note: If there is a virtual inheritance then it’s given higher preference). Then the member fields are constructed. They are initialized in the order they are declared Finally, the class itself is constructed … Read more
