Number in C++
Previous Home Next

Numbers in C++ expressions are interpreted as decimal numbers, unless you specify them in another manner. To specify a hexadecimal integer, add 0x before the number. To specify an octal integer, add 0 (zero) before the number. The default debugger radix does not affect how you enter C++ expressions. You cannot directly enter a binary number (except by nesting a MASM expression within the C++ expression).

// Example to show various number in C++
#include <iostream>
using namespace std;
 
int main ()
{
   // number definition:
   short  s;
   int    i;
   long   l;
   float  f;
   double d;
   
   // number assignments;
   s = 11;      
   i = 1111;    
   l = 1111111; 
   f = 111.11;  
   d = 11111.11;
   
   // number printing;
   cout << "short  s :" << s << endl;
   cout << "int    i :" << i << endl;
   cout << "long   l :" << l << endl;
   cout << "float  f :" << f << endl;
   cout << "double d :" << d << endl;
    return 0;
}

 

// Program to Generate Random Number in C++
#include<iostream>
#include<cstdlib>
 using namespace std;
 main()
{
   int n, max, num, c;
    cout << "Enter the number of random numbers you want ";
   cin >> n;
   cout << "Enter the maximum value of random number ";
   cin >> max;   
    cout << "random numbers from 0 to " << max 
		<< " are :-" << endl;
    for ( c = 1 ; c <= n ; c++ )
   {
      num = random(max);
      cout << num << endl;
   }         
    return 0;
}
