To provide potentially more information about what you may be trying to do, see the following example: class var1 { int a, b; public: var1 operator+( const var1& rhs ) { var1 output; output.a = this->a + rhs.a; output.b = this->b + rhs.b; return output; } }; class var2 { var1 res1, res2; public: var2 … Read more
‘this’ usually refers to the instance of the object that calls a particular method of a class,union,structure or a function. when you have same names for different variables, then ‘this’ is used to differentiate between them. class stu { int roll_no; string name; public: void input(int roll_no,string name) { name=this->name; roll_no=this->roll_no; } } stu obj=new … Read more
*a = *b; The above statement will simply do this: value(a) <– value(b) (i.e. pointer a will contain value ‘d’ ). printf(“%x\n”, a); This will print the pointer’s address(a) in hexadecimal. However, always use the “%p” format identifier to print the addresses. “%x” is used to print the values in hexadecimal format. printf(“%x\n”, *a); Since … Read more
You have overlapping of ‘ quote inside the JavaScript. You need to escape the single quote like this: echo ‘<input type=”submit” value=”Click!” style=”width:100px;” onclick=”$(\’#loading\’).show();”/>’ // Notice the backslashes? ^ ^ 1 solved Echoing html code in php [closed]
You should do it with a switch : public static void main(String args[]) { System.out.println(“Enter 1 to Add, 2 to Subtract, 3 to Divide, or 4 to Multiply”); int x = keyboard.nextInt(); switch(x){ case 1: System.out.println(“Enter an integer”); int num1 = keyboard.nextInt(); System.out.println(“Enter another integer”); int num2 = keyboard.nextInt(); System.out.println(“The sum of the numbers equals … Read more
According to you described above, I don’t think you need any plugins currently. At client side, in order to allow users to provide comments, just create a UI for users to fill comments, and then create a http request (see @angular/http) which submits the gathered comments to somewhere (eg:your can create a server to do … Read more
You can predict your output by following each step manually. In your case, each func call would work like the following chart: func(5) + +–+ func(4) | + | +–+ func(3) | | + | | +–+ func(2) | | | + | | | +–+ func(1) = 3 | | | | | | … Read more
Generally it’s an awful way to write code, and does not guarantee that it will be any faster. Things which are simple and fast in one language can be complex and slow in another. You’re better off either learning how to write fast Python code or learning C++ directly than fighting with a translator and … Read more
according to your update, I guess you do not need the for loop, you need this, demo function countdown(integer) { var time = setInterval(function(){ document.getElementById(“cds”).value=”->”+(integer–)+”<-” if (integer == 0) clearInterval(time); },1000); } 1 solved For loops in JavaScript

It’s not clear exactly what you are trying to do here, except perhaps learning basic c++ constructs. Here is some code to get you going. #include <iostream> #include <string> #include <map> using namespace std; class TEST { public: //Constructor – sets member string to input TEST( string input ) : _name( input ) { } … Read more
a is declared a an empty vector so you cannot access elements of a unless there are any elements in a. You want a.push_back(nums[i]); instead of a[k] = nums1[i]; //a is declared as empty vector so you have to push elements to it. OR you can do vector<int> a(num1.size()); instead of vector<int> a; solved why … Read more

Replace: longitude.indexOf(“E”) >= 0 With: strpos($longitude, ‘E’) !== FALSE And: longitude = longitude.substring(1); With: $longitude = substr($longitude, 1); Just change the variables for other occurrences. This uses strpos() and substr() 1 solved Convert Javascript code to PHP code [closed]
I assume, that you have at least some knowledge of computer programming in some other language then Objective-C. I will talk about this line, but the same problem occurs in several lines in your code if(NSInteger >= 4) You compare the type NSInteger with a number (4).
