Roadmap to C++ Programming

Introduction

There are so many programming languages available in the market, but among them, C++ is something that never lost its charm. It has a powerful impact on the programming world. As per the research, C++ has made its place among the top programming language in the world. As with C programming language, C++ is very easy to understand the architecture of programming language. It also supports some additional features like exception handling and object-oriented programming etc. Top companies like Google, Amazon, Microsoft, etc., offer many career opportunities in C++ programming languages. So we have to start our preparation for those companies. 

C++ wasdeveloped by Bjarne Stroustrup. C++ is a general proposed programming language. It is called the updated version of the C programming language. C++ has the support of the Standard Template Library. C++ language is mainly used for various GUI platforms, Cloud/Distributed Systems, Operating Systems, real-time simulations, etc. C++ is also an object-oriented programming language. It also supports the implementation of object-oriented programming language. We have a strategy to learn the C++ programming language in just 20 days. In this article, we are going to learn that strategy. 

1. Introduction to C++ Programming (Day: 1)-

First of all, we have to learn the C++ programming language with the fundamentals and introduction to the programming language. We have to learn about the features and applications of the C++ language. After that, we have to know how to set up the environment for the C++ programming language. After setup the environment, we can run our first C++ program. Simultaneously we also have to learn about several things, such as the difference b/w C & C++, C++ vs. JAVA, etc. Then we were able to write our first C++ hello world program. 

2. Learn Datatypes, Variables & Operators (Day: 2-3)

After learning the fundamental of the C++ language, we start learning of building blocks of C++. These building blocks are variables, data type and operators. We must learn about data types and how data types are used, what variables are, how variables are declared and initialized, the use of operators in C++, etc. This will helps up know the basics of structure and syntax of C++ programming languages. We should have learned so many other topics, like Operator Overloading, Reference Variables, Optional Parameters, and others.

3. Learn Conditional & Control Statements (Day: 4-5)

After learning the building block of C++, we should start learning about conditional and control statements. We should know about the concept of control flow statements, execution of a block of statements and execution of code based on decision – Decision-Making Statements, etc. We also have to cover so many topics like Loop, While Loop, Do While loop, if, if..else, nested if, etc. There are also so many topics available that are similar to the control statement. These statements are switch statements and jump statements. We have to learn these two statements simultaneously with the control and conditional statement.

4. Understand Arrays, Strings & Pointers in C++ (Day: 6-8)

Once we cover the topic related to datatypes, variables, and other issues, we should start preparing for the concept of string, array and pointer in C++. In C++, an array is used to store the data value, and a string is used to store the text value. A pointer is used to store the data and address of another type of variable. There are so many topics related to string, array and pointer that we should have to learn. These crucial topics are Namespaces, Wild Pointers in C++, etc.

5. Go Through Functions & OOPs Concepts in C++ (Day: 9-12)

After completing the building block of C++, array, string and pointer, we should move towards going through function and OOPs (Object Oriented Programming) concept. Both go through function, and OOPs concepts are an essential topic in C++. We have to know about the functions that are used to perform specific tasks. We have to learn about topics that concern C++, such as function declaration and function overloading. Now we should start preparing for OOPs (Object Oriented Programming) concept, which is a significant topic in C++. This topic includes Class, Objects, Inheritance, Polymorphism, Abstraction, Encapsulation, etc.

6. Learn I/O Streams, Dynamic Memory, & STL in C++ (Day: 13-16)

After completing the OOPs concept, we are now going to learn about I/O Streams, Dynamic Memory, & STL (Standard Template Library). Now we are in the middle of the C++ language. We also have to learn the concept of STL (Standard Template Library), which is a significant feature of C++. In general, C++ is a collection of template classes that provide knowledge of data structure. It also supports the concept of stacks and arrays.

7. Understand Exception Handling, Signal Handling & Multithreading in C++ (Day: 17-20)

After knowing all the above concepts of C++ now, we are in the last part of the C++ programming language. In this part, we learn about some advanced concepts of C++ like Exception Handling, Signal Handling, and Multithreading etc. With the help of the exception handling concept, we can deal with the programming code that throws errors or exceptions. With the help of the signal handling concept, we can pass the signal to the operating system to stop the in-progress task. We also have to learn about the use of POSIX Threads for multithreading in C++.

Conclusion

This is the strategy to learn the fundamental of C++ in 20 days. With this 20 days strategy, anyone can know C++ and be able to make a minor and major project using the C++ programming language.
