Interesting Facts about C++.

-
  • C++ is an object-oriented language.
No. C++ is a multi-paradigm programming language. C++ supports OOP, procedural programming, generic programming, template meta programming and functional programming. It is one of the biggest strengths of C++ that it is a multi-paradigm programming language. Programmers should be free to pick their own programming style, and that style should be fully supported by C++. Why should I define a class just to print “Hello world”?

This quote by Bjarne Stroustrup really makes sense.

    “Certainly not every good program is object-oriented, and not every object-oriented program is good.”

  • C++ is just an extension to C and is a super set of C.
C & C++ both are different programming languages having different rules and standardized by different committees. C & C++ both have diverged since C99. There are many features of C99 and C11 which aren’t officially part of C++ language but some compilers like g++ and clang++ support them as compiler extensions. C++ is not 100% backwards compatible with C. There are many programs valid in C but invalid in C++.

  • Memory management in C++ is error-prone and memory leaks are an annoying issue because C++ lacks garbage collection.
This is an absolutely wrong misconception that mostly Java & C# programmers have about C++. Garbage collection breaks one of the primary design philosophy of C++: "you don't pay for something you don't use." That means if you don't need garbage collection the C++ run-time system should not waste its time cleaning up the whole garbage. C++ programmers must avoid using new/new[]and delete/delete[] most of the time. If you need dynamic array use std::vector. If you need a string then use std::string instead of plain C style char[]/char*.

Bjarne Stroustrup says that:

  Memory is not the only resource. A resource is anything that has to be acquired and (explicitly or implicitly) released after use. Examples are memory, locks, sockets, file handles, and thread handles. A good resource management system handles all kinds of resources. If the release does not happen, we have a leak, and since there is a finite amount of each kind of resource, eventually the system grinds to a halt. You don’t need an actual leak to cause bad effects; excessive resource retention can be almost as bad. For example, if a system holds on to the memory, locks, files, etc., for twice as long, the system needs to be provisioned with potentially twice as many resources.

  • C++ is an outdated and useless language.
C++ is old fashioned language and there is the demand of modern languages like Java, C#, Python etc in the software industry. Right? No, extremely wrong.
C++ is everywhere from the bottom of the ocean to the surface of Mars planet.

C++ is a continuously evolving language since C++11. There is C++14 standard and recent C++ standard is C++17. C++11 feels like a new language as said by Bjarne Stroustrup. C++ standard committee is extremely busy for the next C++ standard which is C++20.

WISH HAPPY HOLI USING C LANGUAGE: follow these steps : 1. open code blocks and select new project: 2. select console application : 3. click on next button and choose c language: 4. provide project title as well as project path: now you can see that the main window is open , so write the code here: #include <stdio.h> #include <wchar.h> #include <stdlib.h> #include <locale.h> int i,j; void delay() {     for(i=0; i<1000; i++)         for(j=0; j<3000; j++)         {} } void delay1() {     for(i=0; i<100000; i++)         for(j=0; j<3000; j++)         {} } void change() {system("COLOR 9");         delay1();         system("COLOR C");         delay1();         system("COLOR 5");         delay1();     ...

How to Start programming.

How to Start programming. First things first, you can't rely on books to learn CS. You need to have access to the internet and online resources. Books are good for the theoretical parts(Data Structures and Algorithms, Discrete Math, theoretical CS, Cryptography, etc. I will tell you about these later on). So, you just need an internet connection to study. So, as I mentioned in an earlier post, C++ is a good start. It's a good language with various applications, its still in use, and its accepted in almost all programming contests. Python is another good language for beginners, but its easy and has got its demerits as a first language(you will find it tough to move to C++ if you know Python as your first language, whereas learning Python after C++ is trivial). I'll tell you a step by step approach to learn programming. 1.  course on C++. There are many other courses on Coursera, Udemy, MITOCW, etc. but they are of some other languages. If you find a ...
