The data type used to store real values

Data Types: A Data type is a type of data. Data types can be used C++ Program.C++ language provides different data types. which can be used in the C++ language program. Data types provide in the C++ library.

Data types are two types in C++ Language 

1. Pre-defined Data Types

2. User-defined Data Types or Derived Data Types.

Pre-defined Data Types: A pre-defined data type is also provided already define in C++ Library. pre-defined data types like integer, floating and Character are pre-defined data types in C++ Language.

Important Same Other Languages Data_Types

👉C Data Types

👉Java Data Types 

👉Python Data Types

Pre-defined data Types Basic Types

1.integer Type (int)

2.floating Type(float)

3.Character Type(char)

User-defined Data Types or Derived Data Types.

1. Pointer Types

2. Array

3. Structure

4. Union

Size of integer Data types

Data Types   Size    Bytes  Range

short                 2      -32768 To +32767

int                      2      -32768 To +32767

unsigned int     2       0 To +65536

long                  4          -214748 To +214748

unsigned long  4      0 To 4,294,967

Size of float Data types

Data Types    Size Bytes  Range

float                4      3.4E-38 To +3.4E+38

double            8       1.7+308 To +1.7E+308

long double   10       3.4-4932 To +1.1+4932

Size of char Data types

Data Types    Size in Bytes    Range

char                           1     -127 To +128

signed char              1     -128 To -128

signed char              1      -0 To + 255

How To Use Data Types Size in C++?

#include <iostream>

#include <stdlib.h>

#include <limits.h>

#include <float.h>

using namespace std;

int main() 

{

int args;

char** args;

cout<<"CHAR_BIT:"<<CHAR_BIT<<"\n";

cout<<"CHAR_MAX:" <<CHAR_MAX<<"\n";

cout<<"CHAR_MIN:"<<CHAR_MIN<<"\n";

cout<<"INT_MAX:"<<INT_MAX<<"\n";

cout<<"INT_MIN:"<<INT_MIN<<"\n";

cout<<"LONG_MAX:"<<LONG_MAX<<"\n";

cout<<"LONG_MI:"<<LONG_MIN<<"\n";

cout<<"SCHAR_MAX:"<<SCHAR_MAX<<"\n";

cout<<"SCHAR_MIN:"<<SCHAR_MIN<<"\n";

cout<<"SHRT_MAX:"<<SHRT_MAX<<"\n";

cout<<"SHRT_MIN:"<<SHRT_MIN<<"\n";

cout<<"UCHAR_MAX:"<<UCHAR_MAX<<"\n";

cout<<"UINT_MAX:"<<UINT_MAX<<"\n";

cout<<"ULONG_MAX:"<<ULONG_MAX<<"\n";

cout<<"USHRT_MAX:"<<USHRT_MAX;

return 0;

}

*****OUTPUT*****
