Output three random numbers using srand(), rand() function

Demo

#include <iostream>  // Declaration of cin and cout 
#include <cstdlib>   // Prototypes of srand(), rand(): 
                     // void srand( unsigned int seed ); 
                     // int rand( void ); 
using namespace std; 
int main() /* w w w. j av a  2s.c o m*/
{ 
   unsigned int seed; 
   int z1, z2, z3; 

   cout << "To initialize the random number generator, " 
         << "\n please enter an integer value: "; 
   cin  >> seed;      // Input an integer 

   srand( seed);      // and use it as argument for a 
                          // new sequence of random numbers. 

   z1 = rand();       // Compute three random numbers. 
   z2 = rand(); 
   z3 = rand(); 

   cout << "\nThree random numbers: " 
         << z1 << "   " << z2 << "   " << z3 << endl; 

   return 0; 
}

Result

The statement cin >> seed; reads an integer from the keyboard.
