## Working with C++ Arrays

Arrays in C++ are one of the most important user-defined data types in C++. They can be used to store a large amount of data of the same data type sequentially. C++ also supports N-Dimensional arrays that can be used for problem-solving in scientific computing. For example, we can use the 2-Dimensional array of C++ to create a matrix, and they have wide usage in NLP, Machine Learning, and Artificial Intelligence. If...

## Calculating Factorial in C++

We will use C++ to write programs to calculate the factorial of a number. We will take the number as an input from the user and then print the factorial of that number in the console. We will use two methods to calculate the factorial of the number, the first is by performing iteration with the help of loops, and the second is by using recursion. ...

## Fibonacci Series in C++ and Python

C++ and Python are the most popular languages of this time. They both are used in Artificial Intelligence, Machine Learning, Scientific Programming, Developing Software, etc. C++ is a swift language, and it is also similar to C and close to the hardware, so we can write very efficient and fast programs using it. ...

## Printing Matrix Spiral in C++

Before coding the example of a matrix spiral, we need to see how to create a matrix in C++. To create a matrix in C++, we use a 2D array, and we can declare it as the following. ...

It’s always never too late to learn new skills. Let’s take some time and look at this fundamental and useful data structure in our daily lives. What is a linked list in C++? It’s a type of data structure that uses pointers for its implementation. It will be very wise for you to also look at pointers if you have not yet since they will give you a deeper understanding of the...

## How to convert string to char array in C++

Converting a string to a character array is simple and straightforward, but before we jump to the solution, we need to identify a few built-in functions we would be using from the string library. ...

## How to convert roman numerals to decimals in C++

To have an in-depth understanding of converting roman numerals into decimals, we must first have an idea about the roman numeral system. It is a number system where letters are used to denote numbers. Modern roman numerals consist of 7 symbols, and each of them has a fixed decimal value. ...

## Stack in C++

The true essence of learning a language is getting familiar with data structures in that language. Data Structure is a fundamental concept as programming is all about storing data, retrieving data, and dealing with data types. The most common data structure we come across is an array. An array is a basic abstract data type that linearly holds data. ...
