C++ vs g++ - C++

What is C++?

C++ is a general-purpose programming language. It was created in 1983 by Bjarne Stroustrup at Bell Labs as an extension of the C programming language. C++ is an object-oriented language, which means that it allows you to create classes that encapsulate data and the functions that operate on that data.

What is g++?

g++ is the default compiler for C++ on most Unix-like systems. It is part of the GNU Compiler Collection (GCC) and is open-source software. g++ can compile both C and C++ code.

Differences between C++ and g++

C++ and g++ are two different things. C++ is a language, while g++ is a compiler. However, there are some differences between the two.

Syntax

C++ has a set syntax that is used to create programs. g++ follows the syntax of C++, but it also has some additional syntax that is specific to the g++ compiler. For example, g++ has an option to compile a program with OpenMP, which is not part of the standard C++ syntax.

Speed

g++ is generally faster than C++ when it comes to compiling code. This is because g++ is optimized for compiling C++ code, while C++ is a general-purpose language that is not optimized for any specific compiler.

Compatibility

C++ code can be compiled with any C++ compiler, including g++. However, code that is specific to g++, such as OpenMP syntax, may not compile with other compilers.

Conclusion

C++ and g++ are two different things. C++ is a language, while g++ is a compiler for C++ code. While there are some differences between the two, they are generally compatible with each other. If you are programming in C++, you can use g++ to compile your code.
