comma

问题 I'm trying to increment a number inside an element on page. But I need the number to include a comma for the thousandth place value. (e.g. 45,000 not 45000) <script> // Animate the element's value from x to y: $({someValue: 40000}).animate({someValue: 45000}, { duration: 3000, easing:'swing', // can be anything step: function() { // called on every step // Update the element's text with rounded-up value: $('#el').text(Math.round(this.someValue)); } }); </script> <div id="el"></div> How can I

问题 I'm trying to understand how the comma operator (,) works in JavaScript, it seems to have a different behaviour when it's not put between parenthesis. Can someone explain me why ? Exemple for reference : var a = 1; var b = 2; var c = (a,b); console.log(c); //output : as expected var c = a,b; console.log(c); //output : 1 [EDIT] The title might be a bit confusing.

问题 I would like to read and write pi as 3,141592 instead of 3.141592 , as using the comma is common in many European countries. How can I accomplish this with iostream s? In other words cout << 3.141592; should print 3,141592 to standard output. 回答1: You should use basic_ios::imbue to set the preferred locale.

问题 What's happening here? #include <iostream> using namespace std; int main(){ int x=0,y=0; true? ++x, ++y : --x, --y; cout << "x: " << x << endl; cout << "y: " << y << endl; //why does y=0 here? x=0,y=0; false ? ++x, ++y : --x, --y; cout << "x: " << x << endl; cout << "y: " << y << endl; } x: 1 y: 0 x: -1 y: -1 The second case seems fine. I would expect both x and y to increment to 1 in the first case but only the left hand operand increments. 回答1: The first one is equivalent to: (true ? (++x,
