In this tutorial, we will be discussing a program to understand File Handling through C++ classes. What's File Handling? File handling is an important concept in programming, which allows a program to read from and write to files. C++ has built-in classes and functions for file handling, which is done ... Read More

In this tutorial, we will be discussing a program to understand Type interference in C++ (auto and decltype). In the case of auto keyword, the type of the variable is defined from the type of its initializer. Further, with decltype, it lets you extract the type of variable from the ... Read More

There are multiple ways to clear/empty an array in JavaScript. You need to use them based on the context. Let us look at each of them. Assume we have an array defined as − let arr = [1, 'test', {}, 123.43]; Substituting with a new array − arr = []; ... Read More
