In this programming example, we will swap two numbers in C++ using call by reference and call by address. in this cpp swap using Numbers Call by Reference. The swap () function is used to swap two numbers.
C++ Program to swap two numbers without third variable We can swap two numbers without using third variable.Exchanges the values of two strings Exchanges the values of string objects x and y, such that after the call to this function, the value of x is the one which was on y before the call, and the value of y is that of x.

Inserting and removing nodes is a simple process that can be done by adding or deleting the desired node and manipulating the pointers of the node before and after it. This is why cpp list are much efficient data containers than deques or vectors in STL.

A "Hello, World!" is a simple program that outputs Hello, World! on the screen. The "Hello World" program is the first step towards learning any programming language. cpp hello world Program Printing the message "Hello World" to the standard output is a classic program that everyone writes when they start learning a programming language.
It's a tradition to start learning programming language with the Hello World program. So, in this tutorial, we'll look at the Hello WorldIn this tutorial, we will learn how to code the Hello World program in C, compile and run it from the command line. program in C and in C++.

What is a cpp map? C++ map is an associative container that is used to store and sort elements in an orderly fashion. C++ map stores information in <key, value> pairs and we can access the value field from the key in O(logn) time. Using the map, you can effortlessly search for elements based on their keys. Keys and values are essential to a C++ map.
Cpp map is a container that stores elements in key-value pairs. It's similar to collections in Java, associative arrays in PHP, or objects in JavaScript. map only stores unique keys, and the keys themselves are in sorted order; Because the keys are already in order, searching for an element is very fast; There is only one value for every key.

The Fibonacci series in c is nothing but a sequence of numbers in the following order: The numbers in this series are going to starts with 0 and 1. The next number is the sum of the previous two numbers. Fibonacci series is a series of numbers formed by the addition of the preceding two numbers in the series.
Fibonacci Series in C using loop A simple for loop to display the series. Program prompts user for the number of terms and displays the series having the same number of terms. In this tutorial you will learn about program for fibonacci series in c. Fibonacci series is a sequence of numbers in which next number in the sequence is obtained by adding previous two numbers.

What Is Tableau?
Tableau is a visual analytics platform transforming the way we use data to solve problems. Tableau helps people and organizations be more data-driven As the market-leading choice for modern business intelligence.
Tableau is a bridge to various data sources which is used to visualize huge data sets. In Tableau, you can directly select the data and switch them between visualizations in one go. It is very fast to deploy, easy to learn and very intuitive to use for a customer. Here is a learning path to all those people who are new to Tableau.

Tableau Public is an application that can help anyone transform small or large data sets into relevant graphs and charts that can then be shared with others and published online. As the word 'public' suggests, the created workbooks can't be locally saved, rather it is sent to Tableau's public cloud which can be accessed by the general public.
This is essentially a free version of Tableau visualization software. It allows you to use the majority of the software functions.You can create visualizations and connect to CSVs, Text and Excel documents. However, the largest difference is that Tableau Public does not allow you to save your workbooks locally.

Regression testing is a type of software testing that intends to ensure that changes to the software have not adversely affected it. Point to Notes. Regression testing is only done when there is any modification or changes become mandatory in an existing project
The regression testing strategy used to share the approach to perform testing that includes testing technique needs to use, completion criteria usage, writing test scripts, and the automation tool that is being used for covering the test cases. Regression testing becomes very important to test whether existing functionality is impacted.

Black-box testing is a one of the software testing methods. Black-box testing examines the functionality of an application without peering into its internal structures or workings.it is also known as functional testing, data-driven testing, and closed box testing.
Black box testing is a software testing technique that focuses on the analysis of software functionality, versus internal system mechanisms. Black box testing was developed as a method of analyzing client requirements, specifications and high-level design strategies.

Slicing in Python is a feature that enables accessing parts of sequences like strings, tuples, and lists. Slicing in Python is a feature that enables accessing parts of sequences like strings, tuples, and lists.
Python provides two overloaded slice functions. The first function takes a single argument while the second function takes three arguments and returns a slice object.

Any natural number that is not divisible by any other number except 1 and itself called Prime Number in Python. For example 2, 3, 5, 7, 11, etc. are prime numbers. Because these numbers divisible by 1 and itself only.

Python input is a built-in function used to read a string from standard input. Python input function allows to user pass content in the program. If the input function is called, the program flow will be stopped until the user has given an input and has ended the input with the return key.
There are many ways to take input from users such as from the keyboard, database, another computer, or mouse clicks. The input from the user is read as a string and can be assigned to a variable.

The Python join method allows an iterable as the input parameter and concatenates their elements into a string with some separator. It is an inbuilt function that returns the string concatenated with an iterable element.
the join() method is the string method that returns the string in which the elements of a sequence have been joined by string separator. The join() method is useful in creating a string representation from the iterable elements.

A Python Array is a number of common type of data structures having elements with same data type. In Python programming, an arrays are handled by the "array" module.
The array module allows us to store a collection of numeric values. In Python, you can create new datatypes, called arrays using the NumPy package.
