In C++, to use a single quote within a string literal, you can escape the single quote with a backslash. For example, to print a string that contains a single quote, you can use this code: cout << "It\\'s a beautiful day" << endl; ...
Explore what is Merge Sort Algorithm in data structure. Read on to know how does it work, its implementation, advantages and disadvantages of Merge sort.
std::cout << "Exception caught: " << e.what() << std::endl;} By defining and throwing your custom exception, you can provide more specific error information and handle exceptional situations in a way that suits your application’s needs. Remember to include appropriate headers and namespace...
Also known as an enhanced for loop in Java or a range-based for loop in C++. It is used to iterate over elements of a collection or array directly without using an index variable. The example inputs produce the output where Apple Banana Cherry is printed on a new line. Example in Java...

The reasons for allowing this may not seem immediately obvious, but a bunch of additional features fall out of this almost by magic. These include de-quadruplication of code, recursive lambdas, passing this by value, and a version of the CRTP which doesn’t require the base class to be te...
