This one was interesting.
I ended up with this:

Thanks~
That idea came from Al Stevens.
I just changed some of it.

[S.Thananchayan]

Unless something random seeds Rand. Rand will generate the same random numbers every time. In this case were using your computers time.
And every time you loop your system time is different So your numbers from say 3:43:01 to 3:43:02 will be different. Random enough for most applications.

Thats awsome I was thinking about this one.
This is the way I was going-
 

C

#include <iostream> #include <algorithm> #include <vector> bool IsThis (int x) { return (x=1);  } bool IsAnswer (int i) { return (((i%10)==2)&(i/100)==2); } int main () {   int mynumbers;   int mycount;   std::vector<int> myscope;   for (int x =100; x<300; x++) myscope.push_back(x);   std::vector<int> myvector;   for (int i=100; i<300; i++) myvector.push_back(i);     mynumbers = (int) count_if (myscope.begin(), myscope.end(), IsThis);    std::cout << "myvector contains " << mynumbers  << " numbers between 100 and 300.n";   mycount = (int) count_if (myvector.begin(), myvector.end(), IsAnswer);    std::cout << "myvector contains " << mycount  << " numbers that begin and end with 2.n";   return 0; }

You need loop to hit random off system time

#include <iostream><br /> #include <ctime><br /> using namespace std;<br /> int main()<br /> {<br />     int a,b,c,d,e,f;<br />     string g,h="a";<br />     srand(time(0));<br />     loop:<br />     a = (rand()%10);<br />     b = (rand()%10);<br />     c = (rand()%10);<br />     d = (rand()%10);<br />     e = (rand()%10);<br />     f = (rand()%10);<br />     cout<<"n";<br />     cout << a;<br />     cout << b;<br />     cout << c;<br />     cout << d;<br />     cout << e;<br />     cout << f;<br />     cout<<"n";<br />     cout<<"n";<br />     cout<<"To create a new random number, press a and then enter.";<br />     getline (cin,g);<br />     if (g==h){<br />     goto loop;<br />     }<br />     cin.get();<br /> }<br />  </ctime></iostream>
