In this article, we have presented two different ways to do Dot Product of Two Vectors in C++. This involves the use of inner_product method in C++ STL (Standard Template Library).

The statement "using namespace std;" is generally considered bad practice. The alternative to this statement is to specify the namespace to which the identifier belongs using the scope operator(::) each time we declare a type.

In this article, we will learn about the concept behind a deque and different ways to initialize a deque in C++ Standard Template Library (STL) like using default constructor, fill, range, move and others.

In this article, we have explained Different Ways to find element in Vector in C++ STL which includes using std::find(), std::find_if, std::distance, std::count and Linear Search.

In this article, we have explained the use of std::swap function in C++ with multiple C++ code examples covering primitive data types to User defined classes.

In this article, we will learn how to get size of 2D vector in C++. This topic has a wide applications such as in graphs, or even in machine learning. Getting used to handling 2D vectors in C++ helps us approach our problems easier.

We have covered the idea of Vector of Pair in C++ with code examples along with basics of Pair and vector in C++.

malloc is a C++ library function that allocates the requested memory and returns a pointer to it. This is called dynamic memory allocation and allows for memory allocation on the go. It is the predecessor to the C++ new operator used for memory allocation.

We have explained the Different Preprocessor Directives in C / C++ along with C++ code examples. Preprocessor Directives are processed at compile time and is an important programming technique in large codebase.

An important aspect of Object-oriented programming is the usage of classes and objects. We have covered different types of classes in C++ such as Standalone classes, Abstract base class, Concrete Derived Class and much more.

In this article, we will begin with a brief recap of what lists are, followed by an introduction to 2-dimensional lists (2D list), where we shall explore creating and defining 2D lists in C++ STL and sorting them.

We have discussed what are 2 Dimensional (2D) arrays and what are the different ways we can initialize them and how we can use them in C++.

We have covered the points of differences between struct and class in C++ with code examples. We have cleared the misconceptions about struct in C language and class in C++.

In this article, we have covered how to pass a vector to a function as function argument in C++ with variants like 1D vector, 2D vector, 3D vector, global vector and global vector by value. We have also, covered how to return a vector from a function.

In this article, we have explained Abstraction in C++ in depth with different types of abstraction and C++ code examples.

In this article, we have explained how to use qsort that is Sorting using stdlib.h in C. We have presented the use-case using code examples.

C99 has defined a set of fixed-width integers that are guaranteed to have the same size on any architecture. These can be found in stdint.h header. This enables to use INT8 in C++.
