1, the operands of predefined operators in C + + can only be basic data types, in fact, for many user-defined types (such as classes), you need to have similar operations. For example, the following program segment defines a complex number class:Class Complex{PublicComplex (double r=0.0,double i=0.0) {real=r;imag=i;}void display ();PrivateDouble Real;Double imag;};So we can declare the object of the plural class: Complex A (10,20), B (5,8);So how do you add to these two objects? We certainly wan
You also need to take into account the problem of one step in the traversal process. This template slides 10 pixels at a time, so a total of 9 slides are required. In addition to the first No. 0 time, the total in the horizontal and vertical direction respectively have 10 such templates, a total of 100 templates. To calculate these 100 templates, the Haar feature on the whole picture can be calculated. And if our step size is set to 5*5, then this computation increases by four times times. In fa

1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test"; 2 function Funcarg () {3 alert (FUNCARG.A
