Study Notes
C++ Basics
- C++ is a general-purpose programming language developed as an extension of the C programming language.
- It was created by Bjarne Stroustrup at Bell Labs in the early 1980s.
- C++ allows programmers to write software that can be compiled and run on many different systems with minimal customization.
- The language started as an extension of C but added support for classes and objects.
- The name "C++" is a wordplay because, in the syntax of C, the ++ operator adds an increment, implying an incremental improvement on C.
Structure of C++ Program
- A C++ program consists of:
- Preprocessor directives
- using namespace std; to allow the use of the standard library
- int main() as the entry point of the program where execution begins
- return 0; to indicate successful completion of the program
Example Program
- An example program to display "Hello welcome to C++" would include:
- #include to include the standard input-output stream library
- using namespace std;
- int main() as the entry point
- cout to display the output "Hello welcome to C++"
