Study Notes
Loops
- A for loop executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.
- A while loop repeats a block of statements while a given condition evaluates to true.
- A do-while loop executes the loop body first before evaluating the expression.
Control Statements
- The break statement terminates the loop or switch statement and transfers the flow of the program to the statements following the loop.
- A switch statement provides a way to perform different actions based on the value of a variable or expression.
- A default statement is a sequence of statements that is performed if no matches are found.
Arrays
- A one-dimensional array is a list of related variables.
Functions
- A function is a group of statements that is executed when it is called from some point of the program.
- A function's body is a block of statements surrounded by the braces { }.
OOP Concepts
- Object-Oriented Programming (OOP) is a conceptual approach to design programs.
- Encapsulation is defined as wrapping up of data and information in a single unit.
- Encapsulation is also defined as binding together the data and the functions that manipulate them.
- Inheritance is the capability of a class to derive properties and characteristics from another class.
- A derived class is a class that inherits properties from another class.
- A base class is a class whose properties are inherited by a subclass or derived class.
- Single inheritance is a type of inheritance that a class is allowed to inherit from only one class.
- Multiple inheritance is a type of inheritance that a class can inherit from more than one class.
- Multilevel inheritance is a type of inheritance that a derived class is created from another derived class.
C++ Basics
- C++ was created by Bjarne Stroustrup.
- C++ was invented in 1979.
- A class is a user-defined data type (a set of states and a set of operations which transition between those states).
- The #include directive is used to include a header file library.
- The using namespace std directive means that we can use names for objects and variables from the standard library.
- A blank line is used to make the code more readable.
- The int main() function is the main function.
- The return 0 statement ends the main function.
- cin is an object used together with the insertion operator ().
- cout is an object used to print output.
Operators
- An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations.
- Arithmetic operators are used to perform common mathematical operations.
- Relational operators are used to compare two values.
- Logical operators are used to determine the logic between variables or values.
- Assignment operators are used to assign values to variables.
