C++ Numbers

Numbers play an important role in almost every program in C++. In general, we uses numbers to perform calculations. Let's see how to define, assign, and then prints numbers in C++

C++ Number Definition

Here is an example, defining some numbers in C++

short int si;
int i;
long int li;
float f;
double d;

C++ Number Assignments

Here is an example, assigning some values (numbers) to the above defined variables

si = 1;
i = 500;
li = 9765625;
f = 65.64;
d = 3878.54;

C++ Number Printing

Here is an example, printing all the numbers, defined and assigned above:

cout<<"si = "<<si<<endl;
cout<<"i = "<<i<<endl;
cout<<"li = "<<li<<endl;
cout<<"f = "<<f<<endl;
cout<<"d = "<<d<<endl;

C++ Numbers Example

Here is the complete version program of the above provided examples

/* C++ Numbers */

#include<iostream.h>
#include<conio.h>
void main()
{
   clrscr();

   short int si;
   int i;
   long int li;
   float f;
   double d;

   si = 1;
   i = 500;
   li = 9765625;
   f = 65.64;
   d = 3878.54;

   cout<<"si = "<<si<<endl;
   cout<<"i = "<<i<<endl;
   cout<<"li = "<<li<<endl;
   cout<<"f = "<<f<<endl;
   cout<<"d = "<<d<<endl;

   getch();
}

Here is the sample output of the above C++ program:
