Why Learn C++? C++ is a powerful object-oriented programming language with the memory-management capabilities of C. Thanks to these incredible features, C++ is used to build high-performance and enterprise-level software. Large companies such as Apple, Microsoft, and Google use C++ to create applications that serve billions of users.In this tutorial, we will learn about objects and classes in C++ with the help of examples. Objects and classesare used to wrap the related functions and data in one place in C++. …Syntax used for capturing variables : [&] : capture all external variables by reference. [=] : capture all external variables by value. [a, &b] : capture a by value and b by reference. A lambda with an empty capture clause [ ] can only access variables which are local to it. Different methods of capturing are demonstrated below :In C++, we can change the way operators work for user-defined types like objects and structures.This is known as operator overloading.For example, Suppose we have created three objects c1, c2 and result from a class named Complex that represents complex numbers.. Since operator overloading allows us to change how operators work, we can redefine how the + … Output. 100 + 78 = 178. In the above program, the add () function is used to find the sum of two numbers. We pass two int literals 100 and 78 while calling the function. We store the returned value of the function in the variable sum, and then we print it. Working of C++ Function with return statement. C++20 modules. C++20 modules require recent C++ compilers such as: Visual Studio ≥ 16.8. GCC or Clang (need added options at this time) CMake ≥ 3.26 is strongly recommended for support of C++20 modules. A fully working ball pit simulation shows more advanced use of C++20 modules.Enter dividend: 13. Enter divisor: 4. Quotient = 3. Remainder = 1. The division operator / computes the quotient (either between float or integer variables). The modulus operator % computes the remainder when one integer is divided by another (modulus operator cannot be used for floating-type variables).So much has changed about the way people make calls. For example, you can’t even call your next door neighbor’s landline without using an area code, and you certainly can’t call mo...C++ Polymorphism. The word “polymorphism” means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form.
