C++ Data types & Variables

C++ Data Types & Variables

Data Type tells compiler that what kind of data we are using if we need to perform Addition between two or multiple Numbers we'll use int (INTEGER), double (point value) , or other data types depending on our requirements. We use data type with variables or as a method return type.
if we need to take Name of a Student or any Character combination of Alphabets then we'll use String or char data type.

Variables are those names which are use to store values of different data types.
value of a variable can be vari it depends on our need.

in C++ every variable of different data type take memory space of heap memory or stack memory to store values of different data types.

Example Program of Variables and data types

#include <iostream>
#include <string>
using namespace std;
int main(){
string name = "ITECH TALEEM";
int rollNum = 101 ;
cout<<"Name : "<<name<<"\n RollNumber : "<<rollNum;
return 0;
}

Console :

Name : ITech Taleem

RollNumber : 101

C++ Classes and Objects Programming

Animated Gif of class and object C++ class and Object A class is a blue print and combination of Different functions and variables. The difference between C and C++ is that C is a procedural programming and does not support classes and objects, while C++ provide support of Object Oriented Programming(OOP) and classes therefore C++ can be called a hybrid language. The variables and functions within a class are called members(variables,functions) of the class. Syntax of C++ Class A class definition starts with the keyword class. For example, we defined the Student data type using the keyword class as follows. class Student { public: string name; // member variables int rollNumber; } A public member can be accessed from outside the class anywhere within the scope of the class object. You can also specify the members of a class as private o...

C++ Pass by Reference and Value Beginner Programming

Animated Gif of Pass by Reference & Value C++ pass by Reference & value There is two way of accessing values of variables and passing values in function argument, first one is pass by value and second one is pass by reference . Reference variable is another name for a existing variable. Once a reference variable is initialized the reference name may be used to refer to the variable. A reference must be initialized when it is created.You can't have NULL references. You must always be able to assume that a reference is connected to a legitimate piece of storage.Once a reference is initialized to an object, it cannot be changed to refer to another object. & operator use to declare reference variable which is use to store variable value, you can access the value of the variable by using original variable name or by using the reference variable. Syntax of Reference variable is very simple //variable initialization int vari = 10; //sim...
