Data Types in C++

Basic Data types: The basic data types are integer-based and floating-point based. C++ language supports both signed and unsigned literals.

The memory size of basic data types may change according to 32 or 64 bit operating system. 

Let's see the basic data types. It size is given according to 32 bit OS.

Data Types	Memory Size	Range
char	1 byte	-128 to 127
signed char	1 byte	-128 to 127
unsigned char	1 byte	0 to 127
short	2 byte	-32,768 to 32,767
signed short	2 byte	-32,768 to 32,767
unsigned short	2 byte	0 to 32,767
int	2 byte	-32,768 to 32,767
signed int	2 byte	-32,768 to 32,767
unsigned int	2 byte	0 to 32,767
short int	2 byte	-32,768 to 32,767
signed short int	2 byte	-32,768 to 32,767
unsigned short int	2 byte	0 to 32,767
long int	4 byte
signed long int	4 byte
unsigned long int	4 byte
float	4 byte
double	8 byte
long double	10 byte

   Derived Data Types: The data-types that are derived from the primitive or built-in datatypes are referred to as Derived Data Types. These can be of four types namely:
• Function
• Array
• Pointer
• Reference

C++ Keywords(की वर्ड )

A keyword is a reserved word. You cannot use it as a variable name, constant name etc. A list of 32 Keywords in C++ Language which are also available in C language are given below.

auto	break	case	char	const	continue	default	do
double	else	enum	extern	float	for	goto	if
int	long	register	return	short	signed	sizeof	static
struct	switch	typedef	union	unsigned	void	volatile	while

C++ Operators(ऑपरेटर्स )

An operator is simply a symbol that is used to perform operations. There can be many types of operations like arithmetic, logical, bitwise etc.

There are following types of operators to perform different types of operations in C language.

• Arithmetic Operators(अर्थमेटिक ऑपरेटर्स )
• Relational Operators(रेलशनल ऑपरेटर्स)
• Logical Operators(लॉजिकल ऑपरेटर्स )
• Bitwise Operators(बिट् वाइज ऑपरेटर्स)
• Assignment Operator(अस्सैंमेंट ऑपरेटर्स) 
• Unary operator(यूनरी ऑपरेटर्स )
• Ternary or Conditional Operator
• Misc Operator
