How To Create Table In Dev C%2b%2b

A Hash Table in C/C (Associative array) is a data structure that maps keys to values.This uses a hash function to compute indexes for a key. Based on the Hash Table index, we can store the value at the appropriate location. The first column in the table will be labeled (index). If data is an array, then its values will be the array indices. If data is an object, then its values will be the property names. Note that (in Firefox) console.table is limited to displaying 1000 rows (first row is the labeled index).

C++ Classes/Objects

C++ is an object-oriented programming language.

Everything in C++ is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.

Attributes and methods are basically variables and functions that belongs to the class. These are often referred to as 'class members'.

A class is a user-defined data type that we can use in our program, and it works as an object constructor, or a 'blueprint' for creating objects.

Create a Class

To create a class, use the class keyword:

Example

Create a class called 'MyClass':

class MyClass { // The class
public: // Access specifier
int myNum; // Attribute (int variable)
string myString; // Attribute (string variable)
};

Example explained

  • The class keyword is used to create a class called MyClass.
  • The public keyword is an access specifier, which specifies that members (attributes and methods) of the class are accessible from outside the class. You will learn more about access specifiers later.
  • Inside the class, there is an integer variable myNum and a string variable myString. When variables are declared within a class, they are called attributes.
  • At last, end the class definition with a semicolon ;.

In C++, an object is created from a class. We have already created the class named MyClass, so now we can use this to create objects.

To create an object of MyClass, specify the class name, followed by the object name.
