data type in c++

C++ has basic data type (int ,float,char,string and boolean). Secondary data type like array pointer and structure etc.

We can also create user defined data types eg : class type object etc.

Primary or basic data type may be declared as following,

#include<iostream>
using namespace std; 
int main()
{ 
int age=25;
float mrp=45.50;
double pi=3.24;
char vowel='a';
string course="c++";
cout<<"age="<<age<<endl<<"mrp="<<mrp<<endl<<"pi="<<pi<<endl<<"char="<<vowel<<endl<<"course="<<course;

output of all data type is as following.

Operator in c++

1. Unary Operator :- only single operand is required to operate.

eg: increment operator ++
( further two types are: pre increment ++a and post increment a++).
decrement operator – – ( further two types are: pre decrement – –a and post increment a – –).

2. Binary Operators :- require two operands to operate.

a. Arithmetic Operators ( + , – , * , / etc ) modules operator % gives the remainder part (eg: 7 % 3 gives 1).

b. Relational Operators ( < , <= , > , >= , == , != )

c. Assignment Operators ( = ) : This operator assigns the right value to the left side operand.

d. Logical Operators:

logical and ( && ) used to combine multiple conditions (return true if all conditions are true).
logical or ( || ) used to combine multiple conditions (return true if any of the conditions is true).
logical not ( ! ) Returns True if condition is False and returns False if it is True.

e.Bitwise Operators ( & , | , ^ , ~ , >> , << ) The bitwise operators are used to perform bit level operations in C++ programming language. When we use the bitwise operators, the operations are performed based on the binary values.

eg: if two variables A and B are:
     A = 25 (11001) and B = 20 (10100)
     then, A & B ⇒ 16 (10000)
