One of the most popular object-oriented programming languages is C++. Stroustrup created C++ by adding object-oriented features to the C programming language.
<h3>How do you write a program in C++?</h3>
- Some people believe that the open-source C++ IDE Dev C++ is one of the finest. However, it may be used exclusively on Windows and macOS. It contains capabilities like profiling, integrated debugging, syntax highlighting, code completion, tool managers, and GCC-based compilers.
- Many people believe that C++, an object-oriented programming (OOP) language, is the finest language for developing complex applications. The C language is a superset of C++.
