What exactly do I mean? C++ is a programming language that allows you to command your computer and make it do whatever you want. This blog is all about what is C++ Programming Language in a short view. If you want to learn more about C++ Programming Language join C C++ Training in Chennai with Certification and placement support.
Before you begin learning C++, the first thing you must do is ensure that you have a compiler. You might be wondering what a compiler is. A compiler converts your software into an executable file that your machine can understand and run.
Introduction of C++ :
A C++ program is a set of instructions that tell the computer what to do. C++ source code, sometimes known as source code or just code, is a set of commands. “Keywords” or “functions” are the two types of commands. Functions are frequently stated in terms of simpler functions, whereas keywords are a basic building component of the language. Thankfully, C++ includes a large number of useful functions and keywords. Join C++ Training in Chennai that helps you to enhance your career.
But how does a program get started in the first place? Every C++ program contains a single function, always called main, that is called when the program first runs. You can call other functions from main, whether they were created by us or were provided by the compiler, as described earlier.
So, how can you get your hands on those pre-programmed functions? The #include directive is used to include a header in order to access the compiler’s standard functions. This effectively copies the contents of the header and pastes them into your program.
Interaction of user and saving information with variables:
So far, you’ve learned how to construct a simple program that displays data typed in by the programmer, as well as how to describe your program with comments. That’s fantastic, but what about user interaction? Your application can also accept input, which is a good thing. You utilize the cin function, which is followed by the extraction operator >>.
Of course, you’ll need a location to store input before you can try to receive it. Variables are used to store input and data in programming. There are various distinct sorts of variables that hold different forms of data (for example, integers versus letters); when declaring a variable, you must mention the data type as well as the variable’s name. Char, int, and float are three basic kinds.
A char variable saves a single character, an int variable stores integers (numbers without decimal places), and a float variable stores numbers with decimal places. Each of these variable types – char, int, and float – is a keyword used to declare a variable.
