Solved: static_cast

Sure, here it goes:

In the world of C++ programming, you often need to convert types. The conversion could be from a simple data type to a complex type, from a derived class to a base class, or from any given type to any other type. C++ provides four casting mechanisms to perform these conversions: `static_cast`, `dynamic_cast`, `reinterpret_cast`, and C++ style cast. In this article, we shall discuss the `static_cast` in detail.

Solved: fill array with 0

Sure, let’s get started.

In this article, we’re discussing a common problem facing developers using the C++ programming language: how to fill an array with zeroes. It’s one of those tasks that seem elementary, yet it’s essential to understand how to execute it properly to maintain optimal code functionality. In C++, there are several methods to fill an array with 0, and we’ll analyze these methods in depth to comprehend their effects on the execution of your code.

In C++, arrays are data structures consisting of elements of the same type, stored contiguously in memory. One of the primary characteristics of arrays in C++ is that they have a fixed size. This fixed-size characteristic often gives rise to situations where we need to initialize or fill an array with a specific value, like 0.

Solved: print std map

Writing software can often be a complex and nuanced task, especially when dealing with data structures like maps in C++. The standard library of C++ provides us with the std::map, which is an associative container that stores elements formed by a combination of a key value and a mapped value, following a specific order.

Std::map is a useful tool for holding key-value pairs in a way that allows a program to quickly look up the value related to a particular key. It does this by automatically sorting its entries by key. Map is commonly used when we need to maintain the data in the form of some sort of key-value pair or if there is uniqueness in our data. They are typically used when searching for values in a dictionary-like way.
