C++ is an object-oriented programming language developed by Bjarne Stroustrup at Bell Labs as an extension of C. It adds object-oriented features to C and is one of the most popular languages for graphical applications used by companies like Mozilla, Adobe, Google, and others. A basic "Hello World" C++ program is shown that uses cout to print to the console and getch to pause the program. Key elements of C++ code like the main function, preprocessor, data types like int and float, and input/output streams like cout and cin are briefly explained.

- 1. C++ Fundamentals Speaker: Jason V. Castellano
- 2. is a low-level programming language developed by Bjarne Stroustrup at Bell Labs. C++ adds object-oriented features, C. C++ is one of the most popular programming language for graphical applications, such as those that run in Windows and Macintosh environments.

- 4. Apple OS X Microsoft
- 5. #include iostream.h #include conio.h Using namespace std; int main() { cout<< Hello world ; getch(); return 0; } // my first program in C++
- 6. #include iostream.h #include conio.h Using namespace std; Preprocessor - a computer program that modifies data to conform with the input requirements of another program.
- 7. main() function it is the function called when the program is run. The execution of all C++ programs begins with the main function int main() { }
- 8. Cout<< - Console Out is a standard output stream cout<<Hello Word; Ex: Output: Hello World
- 9. Cin>> - Console in is a standard input stream cout<<Enter name:; Ex: cin>>name;
- 10. int type used to define numeric variables holding whole numbers. It defines a character primitive type float is a single precision (32 bit) floating point data type is a double precision (64 bit) char float double string generally means an ordered sequence of characters string
