What are the characteristics of C++?

Back

1. High-Level and General-Purpose: C++ is suitable for diverse projects, including system-level programming, game development, scientific computing, and embedded systems. 2. Object-Oriented Programming (OOP): C++ embraces OOP principles, allowing code organization using classes and objects, fostering modularity, reusability, and maintainability. 3. Efficiency and Performance: C++ provides control over hardware resources for performance-critical applications. 4. Compatibility with C: C++ retains compatibility with C, allowing access to its libraries and integration with existing C code. 5. Portability: C++ code can be compiled and executed on various platforms with minimal modifications.

What are the features of C++?

Back

1. Standard Template Library (STL): A collection of pre-built data structures and algorithms that accelerate development and promote code reusability. 2. Rich Standard Library: Includes input/output operations, string manipulation, mathematical functions, and more. 3. Exception Handling: Facilitates graceful handling of runtime errors, improving program robustness and user experience. 4. Operator Overloading: Customizes the behavior of operators for user-defined types, enhancing code readability. 5. Templates: Enables generic programming, allowing code to work with various data types without performance compromise. 6. Namespaces: Organizes code and prevents name collisions, crucial in large projects. 7. Continuous Evolution: C++ undergoes regular updates to improve performance, security, and developer productivity.

What are the basic components of a C++ program?

Back

1. Class Definition: Defines the structure and behavior of objects. 2. public: Makes the main method accessible from anywhere. 3. static: Indicates that the main method belongs to the class itself. 4. void: Indicates that the main method doesn't return a value. 5. main: The entry point of a C++ program. 6. (String[] args): Declares an array of strings for command-line arguments. 7. System.out.println(...): Prints specified text followed by a new line.

What does the 'main' method do in a C++ program?

Back

The 'main' method is the specific name that the JVM looks for when starting a Java program.

Front

What is the purpose of 'System.out.println' in C++?

Back

It is a method call that prints the specified text followed by a new line.

Front

What does 'System' represent in C++?

Back

'System' is a class in the java.lang package that provides access to system resources.

Front

What is 'out' in the context of C++?

Back

'out' is a static member variable of the System class that represents the standard output stream (usually the console).

Front

What does 'println' do in C++?

Back

'println' is a method of the PrintStream class that prints the given argument and moves the cursor to the next line.

Front

What is a string literal in C++?

Back

'Hello World' is a string literal, representing the text to be printed.
