Agile Certification Training: Agile Project Management Framework
If you have been pursuing a career in project management, you may have heard of the terms “kanban, waterfall, agile, scrumban, scrum, and six sigma.” Most companies implement these few popular project management methodologies to streamline their projects. Agile, for example, has become the manager’s favorite framework for projects of all difficulty levels. It offers you flexibility and an easy way to complete tasks by the deadline, within your company’s budget, and maintaining the best quality standards. The agile framework is about collaborating with teams, setting practical and achievable goals, breaking them down into smaller tasks, and communicating the ideas ...
Read MoreAgile Acceptance Test Driven Development: Agile Certification
Acceptance Test Driven Development (ATDD) is an extended version of Test Driver Development (TDD), which promotes the collaboration of different users to verify the functionality of a system. It’s a project management system inspired by agile methodology. It fosters a connection between developers, testers, stakeholders, and clients to understand the system’s function and requirements from the user’s perspective. In this post, we will learn more about ATDD, where the methodology is implemented, its uses, and more. Keep reading. What is Agile Acceptance Test-Driven Development? Contrary to what you might assume from the name, ATDD isn’t precisely a testing procedure. ...
Read MoreC++ Program to Find the Normal and Trace
2-Dimensional arrays or matrices are very much useful in several applications. Matrices have rows and columns and store numbers inside them. In C++ also we can define 2D matrices using multi-dimensional arrays. In this article, we will see how to calculate the Normal and the Trace of a given matrix using C++. The Normal is the square root of the sum of all elements present in the matrix. And the trace is the sum of elements present in the main diagonal. Let us see the algorithm and C++ code representation. Matrix Normal $\begin{bmatrix} 5 & 1& 8ewline 4 ...
Read MoreC++ Program to Print first letter of each word using regex
A useful tool for string operations is regex. This may be found in virtually all high-level current programming languages, including C++. Regular expressions (Regex) are utilized as general-purpose search patterns. For instance, by constructing a straightforward string known as a regular expression, we may implement password validation logic with at least one capital, one lowercase, one number, one special character, and a total length of at least 8 characters. In this tutorial, we'll look at how to use C++ to display only the first letters of words included within a specified string. Here, we'll look at a sentence that uses ...
Read MoreC++ Program to Swapping Pair of Characters
A string is a group of characters. They can be described as character arrays as well. An array of characters can be thought of as strings, and each string has a set of indices and values. The switching of characters at two specified indices in a string is one of the modifications we can sometimes make to strings. In this article, we will see how to swap two characters in a string from two given indices using C++. Syntax char temp = String_variable[ ] String_variable[ ] = String_variable[ ] String_variable[ ] = temp Using indices, ...
Read MoreC++ Program to Replace a Character at a Specific Index
Strings are a collection of characters. We can also say them as character arrays. Considering an array of characters as strings, the strings have specified indices and values. Sometimes we can perform some modification on strings, one such modification is replacing characters by providing a specific index. In this article, we will see how to replace a character from a specific index inside a string using C++. Syntax String_variable[ ] = In C++ we can access the string characters using indices. Here to replace a character with some other character at a specified index, we simply ...
Read MoreC++ Program to Iterate Over an Array
Arrays are data of the same type stored in contiguous locations in memory. To access or address an array, we use the starting address of the array. Arrays have indexing, using which we can access the elements of the array. In this article, we take a look at methods to iterate over an array. This means accessing the elements that are present in an array. Using for loop The most common method of iterating over an array is using for loops. We use a for loop to iterate through an array in the next example. One thing is to be ...
Read MoreHaskell Program to Display Fibonacci Series
This tutorial discusses writing a program to display Fibonacci Series in the Haskell programming language. The Fibonacci series is a sequence in which each number is the sum of the preceding two terms. The Fibonacci series up to five terms is 0 1 1 2 3. In this tutorial we see, Program to print nth fibonacci number. Program to print the first ‘n’ terms in the Fibonacci series. Program to print the first ‘n’ terms in the Fibonacci series using the list comprehension. Program to print the first ‘n’ terms in the Fibonacci series using the map function. ...
Read MoreHaskell Program to Print the Multiplication Table in Triangular Form
This tutorial discusses writing a program to print the multiplication table in the triangular form in the Haskell programming language. For example, the multiplication table for the number 10 in the triangular format is 1 2 4 3 6 9 4 8 12 16 5 10 15 20 25 6 12 18 24 30 36 7 14 21 28 35 42 49 8 16 24 32 40 48 56 64 9 18 27 36 45 54 63 72 81 10 20 30 40 50 60 70 80 90 100 Algorithm Steps Take input or initialize an integer variable ...
Read MoreC++ Program to Sort the Elements of an Array in Descending Order
Arranging data items in a proper form is an essential task while solving some problems in an efficient way. The element sorting problem is one of the most commonly discussed arranging problem. In this article we will see how to arrange the array elements in descending order (decreasing order of their values) in C++. There are many different sorting algorithms present in this domain to sort numeric or nonnumeric elements in a given order. In this article we will see only two simple methods of sorting. The bubble sort and the selection sort. Let us see them one by one ...
