In this blog, we discuss the advantages and disadvantages of using C++.


C++ is an item-orientated computer language created by way of notable computer scientist Bjorne Stroustrup as a part of the evolution of the c own family of languages. It become advanced as a pass-platform improvement of c to offer builders a better degree of manipulating over memory and device sources.

A few name c++ “c with training” because it introduces object-oriented programming principles, consisting of using defined instructions, to the c language framework. Through the years, c++ has remained a beneficial language not most effective in pc programming itself but in teaching new programmers about how object-oriented programming works. However, it does not longer assist most effective item-oriented, but additionally procedural and practical. Thanks to its excessive flexibility and scalability, c++ can be used to expand a vast range of software, packages, browsers, graphical person interfaces (GUIs), working systems, and games.

These days c++ remains very preferred for its top-notch portability which permits developers to create programs that may run on special working structures or systems very without problems. Notwithstanding being an excessive-stage language, in view that c++ remains close to c it can be used for low-level manipulation due to its close relation with device language.


Advantages of C++

  • Portability is one of the main advantages of C++

C++ is a platform-impartial language that offers portability, allowing the programmers to run the identical program on exceptional oss. As an instance, a program code evolved in Linux can be reused in home windows os with no compatibility issues.

  • Object-oriented

C++ brings the concept of an object-oriented approach to programmers using which developers can apply inheritance, polymorphism, abstraction, and encapsulation easily. This means the code developed can be reused in another program utilizing memory resources with the help of constructors and destructors. Having OOPs is one of the main advantages of C++ over C.

  • Low-level Manipulation

C++ is a high-level language closely related to C, as it’s a procedural language and allows low-level manipulation of data at a certain level. A program built in C++ is useful for low-level programming language and efficient performance-wise and memory-wise. Being a high-level language, C++ also offers high-level abstraction.

  • Multi-Paradigm and Faster

A CPP program uses multi-paradigm programming means it follows three paradigms Generic, Imperative, and Object-Oriented. C++ is compiled as it gains a lot of speed over other low-level languages. Compilation of programs in CPP is pre-interpreted and executed faster than its predecessors.

  • Community Support

The more advanced the programming language, the more support is available on the forums and tutorial portals. Numerous platforms provide online courses and lectures for students. For example, students can search free codes and tutorials on w3schoools, StackOverflow, and Github.

Disadvantages of C++

  • Security is one of the common disadvantages of C++

Even though object-oriented programming provides a lot of security to the data compared to C, security issues still exist due to the availability of friend functions, global variables and, pointers.

  • Limitation of Arrays in C++

You need to define the size of an array in advance to store elements. An array has a fixed size which you cannot modify once defined. This means the memory cannot be increased or decreased. Allocating less memory would shorten the number of elements while giving more memory than the requirement leads to wastage of memory space. This limitation is often counted as one of the major disadvantages of C++ programs.

  • Complicated

The syntax in a large CPP program is often complex, and the standard library is small. This can be one of the common disadvantages of C++ as it becomes more difficult to learn for beginners. Also, a program built in C++ is platform-specific which usually turns more complex to debug.

  • No Garbage Collection

A program built in C++ can’t support garbage collection as it does not support Dynamic Memory Allocation (DMA). Also, there is very little memory management in C++, forcing the programmer to do most of it.

  • Linked List also wastes Memory

Like Arrays, a linked list is also defined in advance, which turns out to be another disadvantage of C++ Linked lists. A linked list requires more memory to store the elements than an array. Each node in a linked list points to another reference. Thus it requires additional space in the memory. Also, traversing the nodes in a linked list is not random, which means wasting a lot of time.
