Technology has taken the world by storm and a strong part of the credit for advancement in technology goes to the application developers. Web Development, Data Science, Artificial Intelligence, and many more are the highest-paying fields with numerous job opportunities. To get a job in the web development field, you must have expertise in programming languages.
This tutorial shows you how to Read and Write Excel files in C#. We are going to use Microsoft COM Objects i.e. Excel 16 object in our application. Use the following sample C# source codes for Excel reading and writing. There are multiple examples discussed in this tutorial to read Excel files using C# and write data back to Excel file.
The typedef or “type definition” is a keyword in C or C++ Programming language that allows declaring different names for types such as int or char. It specifies that that the declaration is a typedef declaration rather than a variable or function declaration. In C/C++, any valid data type can be aliased so that it can be referred to with a different identifier.
The Standard Template Library (STL) is one of the most essential features of C++. It has very much grown in recent years. Basically, the Standard Template Library provides templatized, general-purpose classes as well as methods. These classes and functions/methods implement several popular and most commonly used algorithms as well as data structures.
Vectors in C++ are highly versatile sequence containers that provide dynamic resizing and efficient memory management. This guide covers topics ranging from vector initialization to advanced techniques for vector manipulation and acts as a comprehensive resource for developers who want to deepen their understanding of this essential container in C++.
C++ treats files as data streams flowing into and out of a program. Each stream type has its own class, complete with functions that handle reading, writing, and managing file I/O efficiently.
In C++, ternary operator allows executing different code depending on the value of a condition, and the result of the expression is the result of the executed code. The ternary operator uses 3 operands. It evaluates a condition and after that chooses one of its two branches to execute, depending upon the result of condition. The symbol for ternary operator is “? :”. The syntax for the ternary operator is: ? : ;
Simply speaking, polymorphism is the ability of something to be displayed in multiple forms. Let’s take a real life scenario; a person at the same time can perform several duties as per demand, in the particular scenario. Such as, a man at a same time can serve as a father, as a husband, as a son, and as an employee. So, single person possess different behaviors in respective situations. This is the real life example of polymorphism. Polymorphism is one of the important features of Object Oriented Programming (OOP).
The C++ language provides a built-in mechanism, the modulus operator (mod or %), that computes the remainder that results from performing integer division.
This post contains lecture notes of “Introduction to C++” course which is taught at MIT OpenCourseWare. OCW is a free and open publication of material from thousands of MIT courses, covering the entire MIT curriculum. There’s no signup, no enrollment, and no start or end dates.
The goal of these columns is to explore object-orientation through practical object-oriented programming. This time, we look at C++, but in the future we will explore other areas of object-orientation. Learning an object-oriented language-a whole new way of programming-will pave the way for many exciting topics down the road.
