Study Notes
C++ Overview
- C++ is a cross-platform programming language designed for high-performance application development.
- Developed by Bjarne Stroustrup as an extension of the C language.
Programming Language Type
- C++ is a multi-paradigm programming language that supports both procedural and object-oriented programming.
Variable Scope
- Local variables are defined within a function or block and can only be accessed within that scope.
- Global variables are defined outside of all functions and can be accessed from any part of the program.
Portability
- C++ is a portable language, allowing the development of applications that are adaptable across multiple platforms.
Data Types
- C++ supports various data types categorized as:
- Primary (basic types like int, char)
- Derived (arrays, pointers, functions)
- User-defined (structs, classes)
Constants Declaration
- Constants in C++ are declared using the syntax:
const type variable-name = value;
Control Structures
- The
else ifstatement allows for additional conditions to be tested if the precedingifcondition is false. - The
whileloop executes a block of code repeatedly as long as the specified condition remains true. - The
forloop iterates through elements of an array or a collection, providing a convenient way to access multiple elements.
