What is C++?
C++ is an object-oriented programming language that was developed by Danish scientist, Bjarne Stroustrup. Stroustrup created this extension of the C language to support objects and classes (a feature that the C programming language lacks). C++ is a powerful language that has many useful capabilities and support libraries that make it a top contender for high-performance software development.
Due to C++'s main base being sourced from the C language, the two languages are almost entirely compatible with each other. C++ is also compatible with other languages with shared origins or similar syntactical structures. Allowing developers to have manual control over memory is another feature of C++ that is another feature the language has that sets it apart from others. The most desirable feature of C++, however, is its object-oriented programming (OOP) model. OOP is the use of objects and classes to structure code in a way that allows code to be reusable. Although the use of objects and classes are heavily utilized in the JavaScript language as well, there are still a few differences that set them apart.
C++ vs JavaScript
C++ was developed for the purpose of handling high-performance applications while allowing access to memory and certain system properties. JavaScript was created to help developers create webpages and incorporate interactive elements into them. Another major difference between the languages is that C++ is a compiled language, one that will run unless the program is converted into "machine language". JS is an already interpreted language which means that it gets passed through an interpreter that reads and runs the program line by line.
Advantages
The key advantages of C++ may not be extremely obvious at first glance, but they are extremely useful for many coding tasks:
-
Object-oriented allows for better factorization of similar code blocks
- Helps with efficiency, readability, and code manipulation
Precise memory control
Large library support to assist with repetitive programming tasks
Disadvantages
The few disadvantages that set JS and C++ apart will ultimately decide which language is best for your project:
- Manual memory access can be more hazardous or inconveniencing due to the sensitivity of the data and the ease of causing unexpected manipulations
Where is it used?
C++ is used in a multitude of things due to its widespread capabilities as a language. Some technologies as important as space rovers and items we interact with every day include them as well. Below are a few more places where C++ is commonly used:
Video games
Operating systems
Package Managers & Build Systems
Syntax Introduction to C++
/*Library header - allows certain functions to be performed
in C++. This one allows for inputs and outputs to be used.*/
#include <iostream>
/*This is the 'standard library' being declared
to allow access to named variables*/
using namespace std;
int main() { //Main function declaration
cout << "Hello World!"; //"Hello World" output using cout
return 0; //Function must have a return
} //End of function
Conclusion
The language created by Bjarne Stroustrup known as C++, is a very useful language for advanced and high-performance software and applications. With it being a highly compatible language and using objects to maximize runtime efficiency, C++ is undoubtedly a valuable tool for the older and new generations of developers alike.
