[ad_1] Here’s the most const example: class Foo { const int * const get() const {return 0;} \_______/ \___/ \___/ | | ^-this means that the function can be called on a const object | ^-this means that the pointer that is returned is const itself ^-this means that the pointer returned points to a … Read more
[ad_1] You are not printing the upper right part. Change the for loops like this so that you print * for the remaining number if you subtract row from 7 for (row = 1; row <= 7; row++) { for (column = 1; column <= row; column++) putchar(‘*’); putchar(‘ ‘); for (column = row; column … Read more
[ad_1] when user was close the tab or browser means that user can’t online so i want to manage some status using that Online or offline status. You can get hold of the close event window.onbeforeunload of the tab or Browser. And within this event execute a ajax call to server by passing the userId, … Read more
[ad_1] Try using this function that’s a variation of the standard binary_search(). It returns an iterator to the matching element (the ‘lowest’ one) if the value is found in the range, and an iterator equal to last (usually end()) when there’s no match: template< class ForwardIt, class T > ForwardIt binary_search_ex(ForwardIt first, ForwardIt last, const … Read more
[ad_1] This code accepts a decimal value and prints the hexadecimal representation. Try it out yourself In C we can use the %x (%X) format specifier flag to printf to do it for us: printf(“%X”, 16); // 10 printf(“\n”); printf(“%X”, 42); // 2A If you’re using a C++ compiler, we can instead use the std::hex … Read more
[ad_1] Your business logic is a bit unclear, but in regards to the Dictionary object initialization/performance issue, the solution below may serve as a valid alternative. Pertinent to your use-case, you can declare Dictionary<double, int> as shown in the following sample C# code snippet: public static Dictionary<double, int> SampleDictionary =new Dictionary<double, int> { { 3.1, … Read more
[ad_1] I found my own answer to my problem.. By using a Buttons click event and just change the style.. The reason for the Image.MouseUp event was fired was, because it was somehow connected to the Window.MouseUp event.. [ad_2] solved MouseUp event firing wrong [closed]
[ad_1] C++ does not have an associated length property for arrays. (See How do I find the length of an array?) You can do something like this: int length = sizeof(animals)/sizeof(animals[0]); Then, before accessing member variables of elements (like this: animals[i] -> hasFur(true);), you need to first create objects. animals[i] = new Animal(); // assuming … Read more
[ad_1] First, you need to rethink how to reverse a number. Basically, what you want to do is to have a running total starting from 0. Then starting from the rightmost digit in the number to reverse, you 1) Take the total and multiply it by 10. This “moves” the digits of the running total … Read more
[ad_1] Ok. I looked at the source code. And here is what I found. The Abs(-1) part of the expression is always evaluated as a decimal Result = Math.Abs(Convert.ToDecimal( Evaluate(function.Expressions[0])) ); Cos(2) is evaluated as double Result = Math.Cos(Convert.ToDouble(Evaluate(function.Expressions[0]))); And C# does not allow you to add these two types together. The reason that Math.Abs(-1) … Read more
[ad_1] You don’t need to explicitly check against NULL for(i=0; i < 1000; i++) { if(!symbols[i]) // If pointer is NULL then increase the elements numberofelemets++; } 1 [ad_2] solved How to calculate the non-zero elements in the array? [closed]
[ad_1] If you need more precision in your calculations, you can use this library for big nums. Its simple and easy to start and created in C++ with template classes. #include <ttmath/ttmath.h> #include <iostream> int main() { // Big<exponent, mantissa> ttmath::Big<1,2> a,b,c; a = “1234.3323454”; b = “3456.1234534”; c = a*b; std::cout << c << … Read more
[ad_1] I would use App.config and access the settings using the ConfigurationManager.AppSettings class. App.Config <?xml version=”1.0″ encoding=”utf-8″ ?> <configuration> <startup> <supportedRuntime version=”v4.0″ sku=”.NETFramework,Version=v4.5″ /> </startup> <appSettings> <add key=”Setting1″ value=”true”/> <add key=”Setting2″ value=”value”/> </appSettings> </configuration> Access settings from your application with the following bool setting1 = Convert.ToBolean(ConfigurationManager.AppSettings[“Setting1”]); string setting2 = ConfigurationManager.AppSettings[“Setting2”]; To update settings create a … Read more
[ad_1] The answer to the question was: return (T)(object) 999; or return (T)(object) “String”; I call this a “double cast”… [ad_2] solved How do I inject a return type in a method that returns multiple types?
[ad_1] You can do it almost exactly as you described, you were just lacking a few bits. After some minimal fixing, your code would be: public String MapFinder() { if ((Map.Width == 8 && Map.Height==8)) { return “DefaultMap”; } else return “Something Different”; } public String MapTracker() { if( MapFinder() == “DefaultMap” ) // <- … Read more
