Master C & C++ Programming

Variable and Data Types: Variable is a container which works to store data. Data types tell the compiler what type of data will be stored in the variable.

Operators: Operator is a symbol that performs operation on variable and value.

Input and Output Functions: The function of input function is to take data from the user and the function of output is to show information to the user on the screen.

Conditional Statements (If-Else, Switch): If 1 condition has to be checked then if statement is used. If the condition is true then one block is false then if else statement is used to execute the other block. If multiply condition check has to be done then else if ladder has been used.

Loops (For, While, Do-While): Loops are used when a statement or code block has to be executed repeatedly. When a task is performed repeatedly, another loop is selected.

Functions: Function is a block of code that performs a specific task. With the help of function we divide a large program into smaller parts. It is easy to understand, maintain and reuse such code.

Arrays: Array is a data structure that stores multiple values of data types under one variable name.

Pointers: Pointers are special variables that store the memory address of another variable.

Structures: Structures are user defined data types of C programming which help in storing the names of different data types.

File Handling: File handling is used to read, store, update and delete data.

Class and object are the foundation of object oriented programming of C++. With their help we can represent real world entities (Student, Car, Employee, Bank Account etc.) in the program. A class is a blueprint and template according to which objects are created.

Inheritance means using the speciality of one class in another class.

The purpose of Polymorphism is to change the types of functions and objects.

Encapsulation: Encapsulation is an important concept of oops. In physical data variable function method is wrapped inside a class. It is used to secure data and direct access.

Abstraction: Abstraction is an important concept of oops in which only important information is shown to the user. Its basic function is what to do and how to do.

Constructors and Destructors are special member functions of c++, they are used to perform automatic tasks at the time of creation and destruction of the object.

Exception Handling is a technology with the help of which the error exception coming from the program is handled. Because the program suddenly crashes.

Templates: Template is a powerful feature of c++ which supports Generic Programming. Simple word template work Write Once, Use for Many Data Types.

STL (Standard Template Library): STL (Standard Template Library) is a powerful library of c++ which provides pre-built Data Structures and Algorithms.
