Yes, it does cause overflow. Luckily your program is short enough that you didn’t notice the damage. Your code writes 8 bytes into a 4 byte variable. This will scribble on whatever follows a in memory. In your case there are no declarations after a, so it probably wrote over free space, but that’s not … Read more
You might be able to use a binomial distribution if its properties satisfy your needs. It gives you control over the maximum value and the mean. You can even choose a non-integer mean if you want to. You cannot choose the minimum, as that is always zero, so you may have to offset the result: … Read more
It allows you to access properties on an object; In PHP class Car { public $make; public $model; public function setMake($make) { $this->make = $make; } public function setModel($model) { $this->model = $model; } public function getMake() { return $this->make; } public function getModel() { return $this->model; } } $car = new car(); $car->setMake(“BMW”); $car->setModel(“Three … Read more
first you typed example e; So first constructor called and 1 printed example() { cout<<“1”; number = 1; } output : 1 then you typed : e=10 its equal to e = example(10); so another constructor called : example(int value) /// beacause you used example(10) { cout<<“2”; number = value; } so your output is … Read more
You also need to check query is returning data or not , you are facing issue because you are trying to access datarow data which is not present. I hope you got my point. dsOrderDetail = bal.getRecordDisplay(product_id, category_id); if(dsOrderDetail !=null && dsOrderDetail.Table.Count > 0 && dsOrderDetail.Table.Rows.Count >0) { lblProdName.Text = dsOrderDetail.Tables[0].Rows[0][“Product_Name”].ToString() + “<br/>”; lblProdId.Text = … Read more
Solution in C++14, assuming I understood what you meant: template <class Container> constexpr auto byte_size(const Container& container) { using std::begin; using std::end; return (end(container) – begin(container)) * sizeof(container[0]); } Note that this will work even if the container is empty, since sizeof does not evaluate its operand. It won’t work for std::vector<bool> though—guess you’ll have … Read more
String is a class like other classes in any Object oriented programming language and we can create object of it using new keyword like we would do for creating object of any type. In your specific scenario above you have a char array and String class have a constructor overload which take char[] as input … Read more
Your formula can be translated like this: double i = 1; double sum = 0; do{ sum += (1/i + 18*i); i–; } while (i < 16); I’m not really sure that using a do while is the best option, it would probably be better with a for loop like so: double sum = 0; … Read more
tight_contour is a std::vector object containing elements of type std::vector<cv::Point>. The (1) is constructing tight_contour to hold 1 initial default-constructed element. 0 solved What does (1) mean when declaring a vector?
There isn’t an equivalent to decorators in Java. As I understand it, decorators in Python are essentially syntactic sugar for method transformations. For example (from PEP 318): def foo(cls): pass foo = synchronized(lock)(foo) foo = classmethod(foo) becomes this: @classmethod @synchronized(lock) def foo(cls): pass That kind of thing won’t work in Java because Java methods are … Read more
Basically: take the pattern (containing 3 groups), replace instr with second group from pattern. private string MyReplace(string inStr, string leaveStr) { string pattern = @”(.*?)(” + leaveStr + “)(.*)”; string repl = @”*$2*”; Regex rgx = new Regex(pattern); return rgx.Replace(inStr, repl); } string x = MyReplace(@”\textbf\{atext\}”, “atext”); x = MyReplace(@”\textbf\{1\}”, “1”); full string – group … Read more
The problem is _aString=*&c; which is a weird way of writing _aString=c; so that _aString is simply pointing to whatever the function argument was; this class doesn’t manage a the memory for a string (as std::string does), but refers to an external string managed elsewhere. In your test case, that string is a string literal … Read more
It is not clear why you expect this code to behave differently. Look at these lines: var ExchangeRate = c.GrabBTCAmount(); var AmountInBTC = (c.USDtoBTC(15000, ExchangeRate)); var AmountAtMarket = (AmountInBTC * ExchangeRate); If I inline USDtoBTC and inline everything to calculate AmountAtMarket the formula would be AmountAtMarket = (15000 / ExchangeRate) * ExchangeRate So you should … Read more
Introduction Math is a subject that can be difficult to understand and master. It requires a lot of practice and dedication to get it right. Unfortunately, even with all the practice and dedication, sometimes math can still be confusing and mistakes can be made. If you are having trouble understanding why your math isn’t right, … Read more
global variables ——-> data static variables ——-> data constant data types —–> code and/or data. Consider string literals for a situation when a constant itself would be stored in the data segment, and references to it would be embedded in the code local variables(declared and defined in functions) ——–> stack variables declared and defined in … Read more
