How to Learn C++ Programming Language
Written by Mohammad Khalid

C++ is an all-purpose programming language Developed by Bjarne Stroustrup, it can bitterly be known as C language extension. C++ is a popular programming language with all the features and attributes. It is object-oriented and contains all the features that are required in a good programming language. Earlier the language was known as ‘C with Classes’ but now it is popular as C++ meaning C+1. Language is considered a middle-level language because it is the amalgamation of both high and low-level languages.

What is the C++ Programming Language?

C++ is a general-purpose, object-oriented programming language. It allows the programmer to work upon the variety of programs including the development of software and applications. The user has the privilege to create games, operating systems, procedural
programming, and all the full-fledged topics that include the combinations of functions, variables, literals, etc. The key to getting hold of the programming of C++ is practice. Like other languages, C++ beginners are also suggested to start with basic programs after learning the format. The difficulty level should be increased gradually in order to be a perfectionist in the programming arena.

What is Dev C++ is Used For?

Dev C++ is a full-fledged Integrated Development Environment(IDE) and that too free of cost. The developing credit for this programming application can be given to Bloodshed Software till 2005 and then Or well since 2011. It can be downloaded and accessed on Microsoft Windows and Linux Operating systems. It uses Min GW or TDM-GCC 64-bit port as its compiler. This code editor can be successfully downloaded from the official website of Bloodshed Software.

How C++ Compiler Works?

All language compilers have some tasks to perform i.e. to detect the errors in the source program, correct it, and convert it to the machine code for its execution. The C++ compiler’s job is to transform our program in a code language that is understandable by the computer. To make a compiler more efficient, C+= also provides a facility of a linker and pre-defined object code library. Thus, the C++ compiler is a code editor, tester, debugger, linker, and all the facilities of a good compiler.

Online C++ Compiler for Beginners

Online compiling tools can be very helpful to execute the code and blocks of statements if the user does not have a proper C++ compiler. The online compilers allow you to write the snippet as well as to copy-paste the code if written somewhere else. There are many applications and software that promote online compiling for C++. The list is as follows

Paiza.IO
Codiva.io
Compiler Explorer
Sandbox
Quick-Bench
Ideone
C++Shell
TIO
Codepad
Codechef
Jdoodle

Learn C++ Tutorial

C++ is a very good language and is preferred by many users in the field of programming. To learn the working and basics of C++ tutorials are the best methods for the cause. The tutorials tell us about the language’s basics and format. Then they also teach the subscribers the features of an object-oriented language like encapsulation, inheritance, polymorphism, etc. The program structures dealing with different data type sand structured variables and compound data types, classes, objects, and every information related to this are taught in the tutorials available. So, enrolling in a tutorial is a good option to clear every concept of the C++ language.

 Websites and Softwares to Learn C++ 

There are many tools and websites available for beginners to learn C++ coding and polish their programming skills. The list is long but few are given below-

CodeCamp
The Odin Project
CodinGame
Upskill
W3School
SoloLearn
edX
Codeacademy
Udemy

There are many more to join the lists but these are the popular ones. These tools are available online so it is easy for the user to access the course.

C++ list

Lists are the part of the program’s sequential construct which allows the time-to-time correction in a lists sequence. Lists provide better options than array etc for a programmer to work on the extraction, usage, position detector of a memory allocator variable. Lists can be
sequential, doubly-linked and of memory allocating nature. Sequential lists have a linear sequence while storing the memory. A doubly-linked list is a better container as it not only stores the values in a better way but also provides an easy method for its accessing also.

 A Basic C++ Hello World Program

Learning a programming language includes many steps. Mastering the logics, writing the programs, compiling process, saving the file with respective extensions and many more are few tasks. To try hands-on any programming language, beginners choose quite a simple program series. In these simple programs, the simplest program is to display Hello World on the display screen using the language codes. This “Hello World” program is simple regarding the logic because the programmer only needs to type a display statement for “Hello World”. Thus, to start, try this program at the very beginning.

Program:

#include<iostream>

using namespace std;

int main() {

std::cout<< “Hello, World!”<<std::endl;

return 0;

}

Output:

Hello, World!

Linked List in C++ Programming Language

A linked list can be defined as the data structure which stores the values in a linear chain structure. They are of two types- singly-linked and doubly linked. Singly-linked list types structures have a single node which is pointing in one direction, mostly towards the next
element. Doubly linked lists have pointer nodes at both sides for both the previous and the next element of the chain.

How to use C++ Programs

C++ language can be used in many kinds of programs, software building, games applications, etc. For eg- simple programs, array-based including searching and sorting, double and multidimensional array programs for matrices, lists, linked lists programs of both singly list and doubly linked lists, string-based, stack and queue-based, patterns, file handling, mathematical operations, series, puzzles, function, recursion and many more. The programs are innumerable and one program can be written with much different logic.

C++ Coding

C++ is a middle-level language. This feature can be experienced while coding the programs. The code is simple for simple programs and gradually gets difficult with high-level programs. There are some basic principles that should be followed while coding every program. In simple words, we can say that these basic principles are the prerequisite for every coding otherwise the error will be detected. Every programmer is suggested to follow the sequence and basic structures of the program without interfering with the in-built statements. Every program should include a preprocessor directive that is needed in the compilation process. Comments are also an important part of the programs. The comments build an understanding of the program so that everyone could connect with code easily. Moreover, the language is case sensitive which implies that the programmer should be very careful while writing the codes. Thus, proper codes should be written with proper commands so that the program is successfully executed in the language.

Classification of Classes in C++

Classes are like a car that is an object, the accessories are variables and constant, and the driving, seating, and other functions are synonymous with the methods of a program. Thus, a C++ class contains programs. The class creation is necessary before beginning the program. A class can be having a single object or may have more than one object too. The name of the class is accompanied by a keyword class. The class is also used with the access specifiers. The access specifiers can be of three types i.e. public, private, and protected. If there is no access specifier, then the class is called an aggregate class. When the class is given at the top, before the coding starts, then it is called a global class because this class can be used anywhere in the program globally. If the class is defined under any method of any other class, then that kind of class is called the local class.

What is  Modern C++?

Modern C++ can be defined as the C++ language revolutions with the coming decades. These revolutions are based on C++98, C++11, C++14, C++17. The last two numeric digits are the year number when the changes emerged. The versions before 2011 and after 2011 have great differences. There are two resources that contain information regarding these changes. C++ Best Practices is a good resource that tells about the development and the new tools. Then the other resource is the C++ Core Guidelines. This document also contains information on the new versions of C++ and aims to provide users a better knowledge of C++.

Conclusion

C++ is a very efficient language with simple codes. The coding is easy and as the experience of a programmer elevates, the language provides brilliant features to improvise the creativity. There are many books that are based on the concepts involved in C++ programming. Writers have the concept of providing the language’s access to the users efficiently before summing up the matters in books. For eg. ‘C++ Primer’ is regarded as one of the best books when it comes to elevating the programming level in C++ programming language.’ Then Effective Modern C++’ by Scott Meyers is also a brilliant work. It is a good knowledge hub for different versions of C++. There are many more that provides brilliant knowledge in the programming sector regarding the C++ language. These books include ‘The C++ Programming Language’ by Bjarne Stroustrup, ‘Accelerated C++’ by Andrew Koenig and Barbara E. Moo, etc. To build up a career in programming using the C++ language, these books are very helpful for both the beginners and experienced because they provide marvelous study material.
