C++ LANGUAGE DATA TYPES

DATA TYPES 

Normally, when we work with Numbers, we use primitive 
data types such as int, short, long, float and double, 
etc. The number data types, their possible values and 
number ranges have been explained while discussing C++ Data Types. 

Defining Numbers in C++ 

You have already defined numbers in various examples 
given in previous chapters. Here is another consolidated 
example to define various types of numbers in C++: 

#include <iostream> 
using namespace std; 
  
int main () 
{ 
   // number definition: 
   short  s; 
   int    i; 
   long   l; 
   float  f; 
   double d; 
    
   // number assignments; 
   s = 10;       
   i = 1000;     
   l = 1000000;  
   f = 230.47;   
   d = 30949.374; 
    
   // number printing; 
   cout << "short  s :" << s << endl; 
   cout << "int    i :" << i << endl; 
   cout << "long   l :" << l << endl; 
15. NUMBERS 
   cout << "float  f :" << f << endl; 
   cout << "double d :" << d << endl; 
  
   return 0; 
} 
When the above code is compiled and executed, it produces the following result: 
short  s :10 
int    i :1000 
long   l :1000000 
float  f :230.47 
double d :30949.4
